Most migrations don't fail because of bad data, they fail because they are treated like a simple data export, only to discover that the real work was never the data: it always is the logic buried inside every engagement program.
If you are using Marketo, you know it is not outdated. Adobe keeps enriching it with new AI features and advanced ABM capabilities and plenty of teams running complex marketing operations still get real value from it. Yet, a growing number of mid-market B2B organizations are making the switch to HubSpot anyway because it's a trade-off between total cost of ownership, ease of adoption and marketing-sales alignement.
Why marketing teams are leaving Marketo for HubSpot?
At QUANTUM, we observed 3 pressures that show up consistently in migration projects:
- Cost. A Marketo Select license (10,000 to 50,000 contacts) typically runs between $1,000 to $2,000 per month, on top of the Salesforce license Marketo requires to function properly. HubSpot Marketing Hub Professional, by comparison, starts around $890 per month with a native CRM included.
- Operational complexity. Marketo relies on a tight coupling with Salesforce to run sales activity, which multiplies the integration layers a team has to maintain.
- The learning curve. Marketo generally requires dedicated MOps specialists to be used to its full potential while HubSpot is built for broader adoption across marketing and sales teams without specialist training.
One example frequently cited in the industry: PublicRelay consolidated its entire tech stack onto HubSpot after leaving Marketo, and saw 340% revenue growth following full adoption. That result obviously isn't mechanically repeatable: it depends heavily on adoption and execution (that's why where here!) but it illustrates the upside a well-run consolidation can unlock.

When does staying on Marketo still make sense? If your team runs deeply nested, multi-step engagement programs, has established MOps expertise and a clearly positive ROI, the math can still favor the status quo. Migration makes the most sense when your sales CRM is already on HubSpot and Marketo only handles marketing automation: that "split-stack" situation creates sync overhead and attribution gaps that justify consolidation on their own.
A migration doesn't change the data, it changes the logic.
This is the point most underestimated by teams that treat this as a straightforward data migration. A CRM migration (say, Salesforce to HubSpot) is essentially about moving structured records (your contacts, your companies, your deals). The business logic lives in the data itself.
A Marketo migration is different: the logic lives in the programs. A Marketo engagement program isn't a simple exportable record: it's a set of rules, sequences and conditions that need to be rethought.
The 5 stages of a successful migration
1. Audit what you have before touching anything
This is the most strategic step and the one most often skipped. It means building a complete inventory of every Marketo engagement program: program name, number of streams, contacts enrolled (cast size), active status and engagement rate over the last 12 months. This audit sorts every program into three buckets:
- Migrate as-is: active, performing programs.
- Rebuild: inactive but conceptually sound programs, rebuilt natively in HubSpot rather than literally ported over.
- Retire: legacy, broken or irrelevant programs that would only add complexity to the new system with no return.
2. Map fields and data
The two platforms use different terminology for nearly identical concepts (scores, lifecycle stages, programs vs. workflows). This field-mapping stage determines whether scoring and segmentation stay intact once you're live on HubSpot.
3. Rebuild workflows and lead scoring
Replicating Marketo logic as-is inside HubSpot usually produces a system that inherits every bad habit from the environment it replaced. What we often suggest is to rebuild workflows using HubSpot's native building blocks, using the project as an opportunity to retire outdated processes along the way.
4. Migrate the data
Some data doesn't migrate automatically between the two platforms, most notably detailed email engagement history. In that case, teams need to export the relevant reports from Marketo and manually import the key metrics into HubSpot to avoid losing the memory of the customer relationship.
5. Train your teams and secure the go-live
A technically sound project can still fail on adoption. Plan for dedicated training on workflows, reporting (which is structurally different) and day-to-day operations, with internal "super-users" identified in advance. It's good practice to keep Marketo running temporarily as a safety net, then run a post-migration review 30 to 60 days after go-live.
Worth noting: teams that have already run this type of project estimate the real effort is underestimated by about 40% compared to initial plans. Building in that margin at the scoping stage avoids unpleasant surprises on internal resourcing.
The most common pitfalls
- Rushing or skipping the audit step to move faster. It's precisely the step that prevents you from carrying over the old system's mistakes.
- Porting Marketo logic as-is instead of rethinking it with HubSpot's native capabilities (and there are a lot!)
- Underinvesting in team training, even though adoption is what determines the project's ROI.
- Cutting the safety net too early: turning off Marketo before confirming everything works correctly in HubSpot.
- Overlooking engagement history, which doesn't migrate automatically and requires dedicated manual handling.
What HubSpot delivers once the migration is complete
As of 2026, HubSpot's Professional and Enterprise tiers support complex custom objects, ABM tooling and multi-touch attribution (capabilities that previously required staying on Marketo for the most advanced B2B use cases). On top of that, the HubSpot ecosystem (CRM, Marketing Hub, Sales Hub, Service Hub, CMS, Operations Hub) helps teams move away from siloed tools, with a shared customer timeline between marketing and sales.
FAQ · Marketo to HubSpot Migration
How much does a Marketo to HubSpot migration cost? Cost depends on contact volume, the number of programs to rebuild, and the level of support you choose. It's also worth factoring in the licensing savings: HubSpot Marketing Hub Professional (around $890/month) is generally less expensive than an equivalent Marketo Select deployment ($1,000 to $2,000/month), not counting the Salesforce license Marketo requires.
How long does a Marketo to HubSpot migration take? This depends heavily on the number of active programs and the complexity of existing lead scoring. Teams that have run this type of project recommend budgeting around 40% more time than the initial estimate.
Do you lose data when migrating from Marketo to HubSpot? Not if the project is well scoped. Some data, such as detailed email engagement history, doesn't transfer automatically and requires a manual export/import process planned in advance.
Should you keep Marketo active during the transition? Yes, that's good practice: keeping Marketo running in parallel for the first few weeks provides a safety net while you confirm every workflow performs correctly in HubSpot.
In conclusion
Migrating to HubSpot is a full redesign of marketing operations, with governance, training and change-management stakes that matter at least as much as the technical work. Done right (with a serious audit, a rebuilding that copying and real support for the teams involved), it's a chance to start fresh on a cleaner, better aligned foundation.
At QUANTUM, we support marketing and sales teams through their HubSpot-centered CRM projects, from the initial audit through to adoption. Considering a Marketo to HubSpot migration? Let's talk about your context.
