Chapter 01
Why move from Marketo to HubSpot, and when not to
Teams leave Marketo when the power comes at too high a price: a platform that needs a specialist for every change, sits apart from the CRM, and makes reporting a project. HubSpot wins when a company wants marketing, sales, and service in one place, run by its own team, with automation that a marketer can actually build.
It is the right move when you value speed, adoption, and a unified view over raw configurability. It is the wrong move if you run highly bespoke, enterprise-scale automation that truly depends on Marketo's depth and your team has mastered it. A good partner tells you which case you are in before you rebuild a thing.
INSIDEA is an Elite HubSpot Partner, rated 4.99 out of 5 across 450+ verified reviews, and we hold HubSpot's CRM Data Migration and Custom Integration accreditations, two of the five accreditations we carry. The method below is the one we run, not a generic checklist.
Here is the whole migration at a glance, before we go phase by phase.

Chapter 02
What actually moves: the asset inventory
A Marketo move is different from a CRM move, and getting that straight up front saves weeks. Marketo is a marketing automation platform that sits on top of a CRM; it is not your system of record for accounts and deals. So migrating Marketo is mostly about rebuilding marketing logic, programs, forms, scoring, and nurture, inside HubSpot, while your CRM data is handled separately. HubSpot Smart Transfer can migrate HTML email templates from Marketo, which removes a large chunk of manual rebuild.
| In Marketo | Becomes in HubSpot | Watch for |
|---|
| Program and Smart Campaign | Workflow | Logic is rebuilt, not exported |
| Smart List | Active or static list | Filter logic re-created against HubSpot properties |
| Form | HubSpot form | Field mapping and follow-up re-wired |
| Landing page | HubSpot landing page | Templates rebuilt or transferred |
| Email and template | Email and template | HubSpot Smart Transfer can migrate HTML email templates |
| Lead score | Score property plus workflow | Scoring model re-created deliberately |
| Engagement program | Nurture workflow | Stream and cadence rebuilt |
| People and leads | Contacts | The CRM record often lives in your CRM, not Marketo |
| Field | Contact property | Types and picklists mapped |
The trap is treating this as an export. Marketo's programs and smart campaigns do not move as files; the logic is re-created in HubSpot workflows. That is not a loss, it is the moment to simplify automation that had grown into a maze no one fully understood.
Chapter 03
Before you touch anything: the audit
A Marketo migration is decided in the audit of your assets. Mature Marketo instances hold hundreds of programs, smart campaigns, and lists, many dormant, many duplicative. Rebuilding all of it is how a migration turns into a year-long project.
- Which programs actually run? Inventory active programs and campaigns; retire the graveyard rather than rebuild it.
- Which forms and landing pages carry real traffic? Rebuild the ones that convert, not every historical variant.
- What does the scoring model really reward? Migration is the moment to fix a score that stopped reflecting buying intent.
- Which fields and lists feed reporting? Map the ones that matter; leave the rest behind.
Agree the marketing definitions here: what a marketing qualified lead is, when a lead is handed to sales, and what a nurture is meant to achieve. Rebuild the logic you want, not the logic you inherited.
Chapter 04
The migration sequence that protects your history
The sequence is rebuild first, transfer and import second, cutover last. You build the workflows, forms, lifecycle, and scoring in HubSpot, transfer email templates with Smart Transfer and import contacts, then run both systems in parallel to validate sends and deliverability before you switch sending over.
Two facts shape this. HubSpot Smart Transfer can migrate HTML email templates from Marketo, so you do not rebuild every template by hand. And a one or two-way Marketo to HubSpot data sync can keep contacts aligned during the transition, so the marketing rebuild and the contact move do not have to happen in the same hour.
Where the native tools stop, and API or custom work begins
Native tools and Smart Transfer do a lot, but they do not rebuild your logic. Knowing where they stop is what keeps a Marketo move on schedule.
What the native tools and Smart Transfer handle
- HTML email template migration via HubSpot Smart Transfer
- One or two-way Marketo to HubSpot contact sync during the transition
- Field mapping for synced properties
- Standard contact and list data
What needs a deliberate rebuild or custom work
- Programs, smart campaigns, and engagement streams, re-created as workflows
- The lead scoring model, rebuilt as a HubSpot score and workflows
- Forms and landing pages tied to HubSpot follow-up
- Historical email performance, which has no clean one-to-one import
- Complex segmentation and any custom Marketo webhooks or API flows
Chapter 05
Cutover and the first weeks
The riskiest moment in a Marketo move is the switch in sending, not a data cutover. Done well, it is a planned event: workflows are built and tested, templates are transferred, contacts are aligned, and you run a parallel period where a sample of sends and nurtures are validated for deliverability and correctness before Marketo is switched off.
Set exit criteria in advance. Core nurtures fire correctly in HubSpot, forms route and score as intended, deliverability holds on the warmed domain, and the marketing reports leadership uses return sensible numbers. Only then do you move sending fully to HubSpot and retire Marketo.
Chapter 06
Where Marketo to HubSpot migrations break
The failure patterns are specific to marketing automation moves. Almost every troubled Marketo migration traces back to one of these.
!
Rebuilding the maze
Re-creating every dormant program instead of rebuilding the automation you actually want. Audit first.
!
Treating it as an export
Expecting programs and scoring to move as files. The logic is rebuilt in HubSpot workflows.
!
Ignoring deliverability
Switching sending without warming the domain, then watching inbox placement drop.
!
Forms with no follow-up
Migrating forms but not re-wiring the routing, scoring, and nurture behind them.
!
Scoring carried over blindly
Porting a stale score that no longer reflects intent instead of fixing it.
!
Adoption as an afterthought
A rebuilt marketing engine the team does not know how to run. Enablement starts before cutover.
None of these are exotic. They are what happens when a marketing automation migration is treated as a data transfer rather than a rebuild of how marketing runs.
Chapter 07
How INSIDEA runs a Marketo to HubSpot migration
A Marketo move is a rebuild, and we treat it as one. We audit the assets, agree the marketing definitions, rebuild programs as clean HubSpot workflows, transfer templates with Smart Transfer, re-create scoring and forms with their follow-up intact, warm the domain, and run a validated parallel period before sending moves over.
Because we build across CRM, RevOps, growth marketing, and AI, the HubSpot marketing engine you land on is simpler and stronger than the Marketo maze you left. If you want this run as a system rather than a side project, see how we approach HubSpot implementation, or book a strategy call and we will scope your migration against the sequence above.
Chapter 08
Questions people ask
How long does a Marketo to HubSpot migration take?
Most moves run six to twelve weeks, driven by the number of live programs, forms, and templates you rebuild and the complexity of your scoring, not by contact volume. The audit is what lets you forecast it honestly, because rebuilding only what runs is far faster than re-creating everything.
Do our programs and scoring come across automatically?
No, and that is by design. Marketo programs, smart campaigns, and scoring are rebuilt as HubSpot workflows and score properties rather than exported as files. It is the moment to simplify automation that had grown unwieldy, and to fix a score that stopped reflecting buying intent.
What about our email templates?
HubSpot Smart Transfer can migrate HTML email templates from Marketo, which removes most of the manual template rebuild. You still review and adjust them in HubSpot, but you are not starting from a blank canvas.
Will we lose our email performance history?
Marketo's historical email performance does not have a clean one-to-one import into HubSpot. You keep the source data for reference and start fresh reporting in HubSpot; where continuity matters, historical activity can be represented on the contact timeline with custom work.
Should we rebuild ourselves or use a partner?
A small, simple Marketo setup can be rebuilt in-house. The case for a partner grows with the number of programs, the complexity of scoring, deliverability risk, and the need to keep lead flow uninterrupted while you rebuild.
