Marketo to HubSpot Migration: A Demand Gen Guide
By Rome Thorndike | June 2, 2026
Marketo to HubSpot migrations are one of the most common marketing ops projects of the current cycle, driven by three pressures: Adobe's price increases after the Marketo acquisition, HubSpot's consistent product investment at the mid-market tier, and demand gen teams burning out on Marketo's dated interface. The migration is real work, and most teams underestimate it by about 40%.
This guide covers what the project actually involves, where it breaks down, and a week-by-week checklist built from how demand gen teams approach it in practice.
Before You Decide: Is the Migration Worth It?
The migration argument is strongest when your demand gen team is on HubSpot's CRM for sales but using Marketo for marketing automation. That split-stack situation creates data sync headaches, attribution gaps, and constant ops overhead. Consolidating onto HubSpot eliminates the sync layer and simplifies the data model.
The argument is weakest when your team has built deep Marketo expertise, runs complex multi-step engagement programs with nested smart campaign logic, or relies on Bizible for multi-touch attribution. HubSpot does not replicate Marketo's smart campaign logic directly, and HubSpot's attribution reporting, while improved, is not a full replacement for Bizible.
Run the numbers before you commit. Marketo typically runs $1,000 to $3,000+ per month depending on database size and features. HubSpot Marketing Hub Professional starts at $890 per month (3 seats). The savings are real, but subtract the migration cost ($30K to $70K all-in for a mid-market team) and you are often looking at a 12 to 18 month payback period in year one.
What You Are Actually Moving
A Marketo instance contains several categories of assets that require different migration approaches.
Contact and lead data. Your database exports cleanly from Marketo as a CSV and imports into HubSpot using the native import tool or a middleware connector like Syncari or HubSpot's own Operations Hub. Custom field mapping takes time but is rarely the hard part.
Email templates. Marketo's email template system uses custom HTML modules and variables that do not map to HubSpot's drag-and-drop editor or coded templates. Plan to rebuild every template. Teams with 20+ active templates often spend 3 to 5 weeks on this alone.
Smart campaigns and programs. This is where migrations get complicated. Marketo's smart campaigns use trigger and filter logic that is more granular than HubSpot's workflow conditions. Complex scoring programs, engagement program branching, and operational data management campaigns often require rethinking the underlying logic rather than direct translation.
Lead scoring models. Marketo allows multi-dimensional scoring with behavioral decay, demographic scoring, and complex filter combinations. HubSpot's scoring tool is simpler and does not support decay natively (you can approximate it with workflows, but it requires ongoing maintenance). Budget significant time here.
Landing pages and forms. If your landing pages are built in Marketo, you will rebuild them in HubSpot. The good news is HubSpot's landing page editor is meaningfully better than Marketo's. The bad news is that every active landing page URL changes, which breaks links in emails, paid ads, and social content.
Salesforce integration configuration. If both platforms integrate with Salesforce, you will reconfigure field mappings, sync rules, and lifecycle stage transitions. Plan a full day with your Salesforce admin to audit and rebuild the integration.
Week-by-Week Migration Checklist
Weeks 1 to 2: Audit your Marketo instance. List every active program, smart campaign, email template, landing page, and form. Document the lead scoring model in full. Identify which assets are actively used and which are legacy artifacts that do not need to migrate.
Weeks 3 to 4: Data mapping and field setup. Map every Marketo field to a HubSpot equivalent. Create custom properties in HubSpot for fields that do not exist natively. Export a contact sample and test the import. Configure the HubSpot-Salesforce integration in your sandbox environment.
Weeks 5 to 7: Rebuild core assets. Start with the highest-traffic email templates and landing pages. Rebuild scoring in HubSpot, accepting that you will simplify the model. Rebuild the three to five most critical nurture programs. Do not try to rebuild everything before going live.
Weeks 8 to 10: Parallel run. Both systems stay active. Run new leads through HubSpot while existing Marketo programs continue. Compare outputs weekly. Check that lead scoring, data sync, and reporting match expectations. Fix discrepancies before full cutover.
Weeks 11 to 12: Cutover. Turn off Marketo programs, redirect landing page URLs, update all email and ad links, and switch new lead routing to HubSpot. Keep Marketo active for 30 days post-cutover as a safety net. Cancel the contract after validation is complete.
What Usually Goes Wrong
Scoring drift is the most common post-migration problem. The rebuilt scoring model produces different MQL volumes than Marketo did, usually more MQLs at lower quality because HubSpot's simpler scoring logic cannot replicate Marketo's disqualification filters. Budget 4 to 6 weeks post-cutover to recalibrate thresholds and filters based on actual sales feedback.
URL breakage is predictable but teams still miss it. Every Marketo landing page URL that changes needs a redirect. Every email that links to a Marketo page needs updating before the new system goes live. A URL audit spreadsheet before cutover prevents the worst of it.
Attribution gaps during the transition period. Any deal that touches both systems during the parallel run will have incomplete attribution data. Most teams accept this as a known gap and document the transition period in their attribution reports.
HubSpot vs Marketo After Migration
Teams that complete the migration typically report that HubSpot is faster for day-to-day execution: email creation, landing page builds, and campaign setup are meaningfully faster than Marketo. Reporting at the contact and campaign level is easier to access. The tradeoff is the program-level attribution and sophisticated scoring that Marketo does better.

Frequently Asked Questions
How long does a Marketo to HubSpot migration take?
For a mid-market demand gen team running 10 to 20 active programs, plan 8 to 16 weeks total. That includes 2 to 3 weeks of discovery and data mapping, 3 to 5 weeks of workflow rebuild, and 4 to 6 weeks of parallel-run validation where both systems stay live. Smaller teams with simpler workflows can complete in 6 weeks. Enterprise teams with complex lead scoring, multiple product lines, and Bizible attribution can run 20+ weeks.
What is the hardest part of migrating from Marketo to HubSpot?
Lead scoring is the biggest pain point. Marketo's smart list logic uses AND/OR conditions across behavioral and firmographic data in ways that do not map cleanly to HubSpot's workflow conditions. Demand gen teams that built sophisticated scoring models in Marketo typically spend 30 to 50% of the total migration effort rebuilding scoring logic in HubSpot, and they still end up with a simpler model than they started with.
Does HubSpot have all the Marketo features demand gen teams need?
For most mid-market demand gen teams, yes. HubSpot's marketing hub handles email automation, lead scoring, landing pages, forms, and multi-touch attribution well enough for typical programs. Where Marketo still wins: deeply nested smart campaign logic, granular program-level attribution with Bizible, and complex multi-step engagement programs with sophisticated branching. If you rely heavily on those features, HubSpot will be a step down.
What does a Marketo to HubSpot migration cost?
Agency-led migrations typically run $15K to $50K depending on complexity. Doing it in-house with a dedicated marketing ops manager and 2 to 3 months of their time is often $20K to $40K in loaded labor. Add platform overlap (you will pay for both during the transition, typically 2 to 4 months) and training time for the team. Total cost for a mid-market team is usually $30K to $70K all-in.
Should you migrate from Marketo to HubSpot at all?
Only if cost or usability is a real problem. Marketo's main weaknesses are its UI (outdated compared to HubSpot) and its price (typically $1,000 to $3,000+ per month versus HubSpot Marketing Hub Professional at $890 per month). If your team is productive in Marketo and the cost is manageable, the migration ROI is often negative in year one after you factor in disruption, parallel-run costs, and the capability gaps during transition.
