How long does a marketing automation migration take?

Few buyers say how long the build took; the four who did describe implementation milestones from about a month to roughly a year and a half, and the largest consolidations were still under way. The faster moves were small in scope and led by someone who had used the new platform before. Some teams also revisit their implementations surprisingly soon — through rework, consolidation, another migration or a new evaluation. What sets the speed, from the buyers who ran these migrations.

Based on verified interviews with the marketing operations, demand generation and digital leaders who plan and run marketing automation migrations, at DTC and enterprise brands. Buyers are anonymized before publication; vendor names and views are reported as given. No vendor paid to appear or could edit this page.

Ask buyers how long their marketing automation migration took and few give a build time, and those who do measure to different points: a month to migrate, eight months from signature to go-live, a migration still nearly finished at nine months, eighteen months to implement. The longest projects here — moving many brands, or folding several platforms into one — were still running. What sets the speed is mostly scope, the CRM connection and who leads the work: the quick moves in these interviews were all led by someone who had used the destination platform before. Go-live is not the finish, as with CDPs: buyers describe a year or two of building programs and fixing the CRM sync afterwards. And the platform is often not settled for long — several teams started their next change within a year or two of the last. This page covers platforms bought for lead management and nurture; consumer email-sending moves are on email migration timelines, and the boundary is on what is marketing automation. The companion reads are why companies switch marketing automation platforms and what marketing automation buyers wish they'd known, where the ratings live.

1 to 18 mo
Four buyer-reported implementation timelines, each to a different milestone; one was nearly finished at nine months. Examples, not a typical range.
Prior experience
The completed faster moves had leads who knew the destination platform, and limited scope. Experience may have helped; the interviews cannot isolate it.
Revisited quickly
Several teams reported rework, another migration, consolidation or a new evaluation within roughly one to two years — different outcomes, not all completed switches.
Where the time goes in a marketing automation migration Before the build: about a month of approvals, two to three months trialling a platform that was then rejected, and a couple of years building the case. Four reported implementation milestones: about a month to migrate, about eight months from signature to go-live, more than nine months elapsed in a migration that was nearly finished, and about eighteen months to implement. After go-live: a rebuild within a year, still at the start of the curve after eighteen months, and about two years before the platform began to show value. BEFORE THE BUILD Approvals about a month Trialled, then rejected 2–3 mo Building the case a couple of yrs THE BUILD · REPORTED IMPLEMENTATION MILESTONES To migrate about 1 mo Signature to go-live about 8 mo Nearly finished 9+ mo elapsed To implement about 18 mo AFTER GO-LIVE Rebuilt within a year Still at the start 18 mo on Over the hump about 2 yrs 0 1 yr 2 yrs
Each row represents one company's reported project. The first group covers activities before implementation. The second shows four buyer-reported implementation timelines measured to different milestones: migration completion, contract signature to go-live, a project nearing completion, and implementation completion. The nine-month example was still under way at the reported milestone; a later interview confirms the switch but gives no finish date. The third group shows elapsed time after go-live to the operational status buyers describe. These are different measures, not comparable end-to-end migration durations.

What sets the speed of a marketing automation migration

01

The scope: several brands, markets or platforms at once

The longest projects here are consolidations: several platforms folded into one, or many brands and markets moved in turn. One company moving many brands, about a year and a half in, was “still in the process of onboarding all the brands and markets onto the Marketing Cloud.” A multi-brand group built by mergers was “halfway through the transition to the HubSpot platform” and expected to finish within the year. As with commerce and CMS migrations, many units mean waves, and waves mean time.

02

The CRM connection

Marketing automation lives on the CRM's data, and connecting the two sets the pace. A global B2B manufacturer's move to Marketing Cloud “did take us a long time to integrate their solution into our ecosystem,” and “A lot of that had to do with integrating it with so many other systems that we had.” At a fintech's B2B side, “since we've only been using it for a couple of years now, we're just getting things like the syncing between Marketo and Salesforce to work.” Some migrations simply run on the CRM's schedule — a go-live onto Marketo alongside a new CRM, or a consolidation tied to a CRM merger. Why the sync drives moves in the first place is on why companies switch marketing automation platforms.

03

Data quality

The records that move decide how long the move takes. A financial-services company consolidating its platforms says “Our biggest challenge is going to be data quality,” and “So the data is going to be definitely our number one constraint.” The multi-brand group was “still in the process of migrating the data and setting up the customer journey.”

04

A small team on top of the day job

Marketing automation migrations are often run by a few people who also run the programs. The financial-services company, eight months into folding several platforms into one, had a fraction of the dedicated staff its leader says a move that size needs, and was still looking for a program manager. A regional health plan runs its platform with a small team and is “actively looking to how we support Marketing Cloud with more resources versus trying to get out of it.” As with CRM implementations, the same people carry the business and the project.

05

Learning the platform, and replacing what it dropped

A new platform takes training, and some of what the old one did does not come across. The manufacturer found Marketing Cloud “a bit clunky to work with because it does require a whole bunch of training for you to get certified to use it,” and another team was “still just getting used to how to use Marketo.” A national health insurer lost webinar hosting and web analytics in its move and is buying them back. As with CMS migrations, what the old platform did has to be rebuilt; why it takes specialists to run these platforms is on the lessons page.

How long does a marketing automation migration take?

These interviews do not establish a typical migration duration. Four buyers give usable implementation timelines, and they describe different milestones: about a month to migrate a small team from Marketo to HubSpot with an agency's help; about eight months from signature to go-live for a Marketo implementation alongside a new CRM; more than nine months elapsed in a Marketo-to-HubSpot migration that was “nearly there” — a later interview confirms the switch but gives no finish date; and about eighteen months to implement Salesforce Marketing Cloud at a global manufacturer. Three describe completed milestones; the nine-month project had not been reported finished at that point. The longest projects here were still running — a brand-by-brand move about a year and a half in, and a consolidation of several platforms eight months in. The quickest moves were small teams and the longest were enterprises consolidating; that is size and scope, not the vendor. Before the build there is its own clock, from about a month of approvals to a couple of years building the case, as with loyalty programs.

What did the faster migrations have in common?

The faster or accelerated implementations here shared two characteristics: relatively limited scope, and a lead with prior experience of the destination platform. A completed Marketo-to-HubSpot migration took about a month with an experienced lead and a familiar agency — the B2B data company's marketing lead, a long-time HubSpot user, says “and then I had 30 days to migrate off of Marketo into HubSpot,” and “I brought in an agency that I've worked with in the past to help us do that.” An executive who had run Marketo at several companies met an accelerated go-live, “within eight months from the time that we signed to the time that we actually deployed it, which is very aggressive.” A startup still early in its migration expected to move quickly because its lead already knew Marketo — “I have more expertise in Marketo, so I can spin up a lot really quickly in Marketo” — though its final implementation time was not yet known. These examples suggest prior familiarity may help teams implement more efficiently, but the interviews cannot separate it from project scope, partner assistance or other differences, and we cannot tell whether the slower projects lacked that experience. They do not establish that experience caused the faster outcomes.

Is a marketing automation platform finished at go-live?

Not in buyers' telling. A regional health plan says “Even though we've had it implemented for 18 months, we're still kind of at the beginning part of that curve.” The global manufacturer, about two years after deciding, is “just getting over the hump now where it's beginning to show real value or beginning to incorporate it into our solutions.” At a fintech's B2B side, “there would be a huge onboarding burden that I think the teams are still just now overcoming, a couple years afterwards.” As with CDPs, go-live is not the finish.

How soon do teams revisit a marketing automation implementation?

Some teams revisit their marketing automation technology within a year or two of implementation, although the outcomes differ. A large bank's B2B team began rebuilding a messy implementation within a year — which does not necessarily mean it changed vendors — finding that once “the implementation and the setup was done, and within a year, we had to start backing out and redoing it because it was really messy.” A software startup began moving to Marketo after less than a year on its previous tool. The financial-services company began consolidating a B2B instance set up about a year earlier, with further migrations still planned: “For B2C, we will also do a full migration over and we will sunset those at the end of 2027 as part of our contract with Salesforce.” And one manufacturer started evaluating alternatives about two and a half years after its previous migration. These examples show how quickly implementation decisions can be revisited, not how often companies complete another switch; the interviews do not establish a typical time between marketing automation migrations. Why teams move is on the switching page.

Do marketing automation migrations stay on schedule?

Too few buyers compared the outcome with a plan to say. Of the two who did, one met an accelerated eight-month date and one “it did take longer than expected,” as its leader put it, with no planned date to size it against. Several more had dates still ahead of them at the interview. Two cases cannot show how often these migrations finish late.

The stories behind the timelines

A national health insurer consolidated two marketing automation platforms into one, and one director described it across three interviews. The first framed the decision: “that's the driving factor is the leadership question is, why do we have both vendors?” — and the testing on both sides. A second interview, six months on: “It's a big transition for us, and it's taking quite some time and it's continuing to.” A third, five months after that: “We've actually flipped off the switch for Marketo, even though we still have some limited access to it.” Some of what the old platform did had not come across: “With our migration to Salesforce Marketing Cloud, it went away, and we're trying to get it back.” Marketing director · national health insurer
A financial-services company is folding several marketing platforms into one suite. The constraint is the records: “Our biggest challenge is going to be data quality.” The team running the move is short of the people it needs, eight months in. Not everyone is glad to see the old tools go — “If I had my way, we would not be decommissioning Pardot.” The plan has two parts: “We will move the B2B journeys that are built over there into Marketing Cloud Advanced and Data 360 out of the Marketing Cloud Next umbrella of the Salesforce products,” and consumer instances will follow by a contract date. Marketing technology manager · financial-services company
A regional health plan finished its move to Marketing Cloud and is still building on it. “We just finished migrating to Marketing Cloud about 18 months ago, so we're really focused on continuing to build out skill sets and resourcing around that.” The work is basic for now: “We really took this year to just try to build out our template library and get the basics down.” The plan is to invest rather than leave: “No, we're actively looking to how we support Marketing Cloud with more resources versus trying to get out of it.” Digital marketing director · regional health plan

The counter-current: the moves that went quickly

The quick moves here share a shape: a small marketing team moving one brand to a platform its leader knew, usually with a partner the leader had worked with before. One went from contract to migrated in about a month; another met an aggressive eight-month go-live onto Marketo alongside a new CRM, which the executive credited to “the partners as well as the enablement team that helped us bring it all together.” Nothing quick here involved a consolidation, several brands or markets, or a move into Marketing Cloud.

What this means for your migration plan

In these interviews the length of a marketing automation migration is set by scope, the CRM connection and who leads the work more than by the platform. Our recommendations, not practices buyers describe: map which brands, markets and platforms move together and date each wave separately; test the CRM sync with your own records before setting a go-live date; list what the old platform does that the new one will not — webinars, analytics, lead scoring — and budget to replace each; if nobody on the team has run the destination platform, bring that experience in through a partner or a hire before you set a date; and count the year after go-live in the plan, since building programs and fixing the sync continue long after cutover.

Common questions

How long does a marketing automation migration take?

These interviews do not establish a typical duration. Few buyers say how long the build took, and the four who give a timeline describe different milestones: about a month to migrate for a small team moving from Marketo to HubSpot with an agency, about eight months from signature to go-live for a move onto Marketo alongside a new CRM, more than nine months elapsed in a Marketo-to-HubSpot migration that was nearly finished, and about eighteen months to implement for a global manufacturer's move to Marketing Cloud. Consolidations across many brands or platforms were still running.

Why do marketing automation migrations take longer than planned?

Buyers point to the scope — several brands, markets or platforms at once — connecting the new platform to the CRM and other systems, data quality, a small team running the project on top of the day job, and features of the old platform that have to be learned or replaced.

What did the faster marketing automation migrations have in common?

The faster or accelerated moves in these interviews had limited scope and a lead who had used the destination platform before, often with a partner they knew. Experience may have helped, but the interviews cannot separate it from scope and partner support, so they do not show that it caused the speed. Planning for that experience — through a partner or a hire — before setting a date is our recommendation, not a practice buyers describe.

Is a marketing automation platform finished at go-live?

Not in buyers' telling. They describe a year or two afterwards of building templates and nurture programs, getting the CRM sync to work, re-buying features the old platform had, and learning the platform; one health plan was still at the start of the curve eighteen months after finishing its migration.

Do marketing automation migrations stay on schedule?

Too few buyers compared the outcome with a plan to say. Of the two who did, one met an accelerated eight-month date and one took longer than expected; several more had dates still ahead of them at the interview.

How soon do teams revisit a marketing automation implementation?

Some within a year or two, with different outcomes: in these interviews one team began rebuilding its implementation within a year of launch without necessarily changing vendors, one began moving after less than a year on its previous tool, one began consolidating an instance set up about a year earlier, and one started evaluating alternatives about two and a half years after its last migration. These are not all completed switches.

Methodology. Alium conducts verified interviews with software buyers — the marketing operations, demand generation, digital and marketing leaders who select and run these platforms. This page aggregates what buyers in that corpus, through October 2026, say about the time it takes to move to, consolidate onto or rebuild a marketing automation platform used for lead management and nurture — Marketo, Pardot (Account Engagement), Eloqua, HubSpot Marketing Hub, Act-On and Salesforce Marketing Cloud where it runs as the lead-generation platform. Consumer email-sending moves and sender warming are covered on the email migration timelines page instead, and HubSpot or ActiveCampaign used as a CRM on the CRM page. Projects are confirmed in the buyer's own words and counted once per company; each is coded as completed, underway or planned, and plans and the time before a build are kept apart from build times. Few buyers time the build, and the ones who do measure to different endpoints, so durations are reported as examples with their status rather than as typical ranges. Ratings for these platforms are on the marketing automation lessons page rather than here. Buyer identities are verified at interview time and anonymized before publication; vendor names are reported as given. No vendor paid to appear or was able to edit this page.
