The Phase-by-Phase Timeline
The 6-10 week band we quote on the migration service page breaks down into five phases. The ranges below assume a mid-market instance: one workspace, one Salesforce org, tens of active programs.
- Weeks 1-2: audit and inventory. Count what is actually live: active smart campaigns, forms in use, integrations firing, fields the sync actually writes. This inventory decides the rest of the timeline; skipping it is how migrations blow their estimate.
- Weeks 2-4: foundation build. HubSpot portal configuration, property architecture mapped from Marketo fields, Salesforce sync built clean rather than replicated, lifecycle stages defined.
- Weeks 4-7: program and asset rebuild. Active campaigns rebuilt as workflows, emails and landing pages recreated on HubSpot templates, forms swapped on the website, scoring model rebuilt and validated in parallel.
- Weeks 7-9: cutover. Contacts and activity history imported, routing switched, Marketo forms retired, both platforms monitored side by side.
- Weeks 9-10: decommission and handover. Marketo contract wind-down, documentation, team training on the new workflow model.
What Extends the Timeline
Three multipliers show up again and again. Multiple Marketo workspaces or partitions add configuration and deduplication work. A Salesforce sync carrying years of field drift means the mapping phase doubles, because nobody remembers what half the fields do. And velocity assets (operational programs, data normalization campaigns, country-picklist cleaners) have no HubSpot equivalent and need rethinking, not copying.
What Breaks When You Rush
The failure pattern we see in rescue engagements is consistent: the data moved, the logic did not. Contacts and templates arrive on schedule; then MQLs stop routing because lifecycle stages were never wired to the new score, sales loses activity history because the sync was replicated instead of rebuilt, and nurtures silently stop because enrollment criteria were translated literally from smart list logic that works differently in HubSpot.
The fix is sequencing, not heroics: scoring, lifecycle, and sync are rebuild work, and they belong in the plan with their own weeks, not as an afterthought during cutover week.
Is the Migration Worth It?
Depends entirely on your size and complexity, which is why we wrote a vendor-neutral Marketo vs HubSpot vs Pardot comparison. Teams that migrate down-market typically cut license spend by 30-60%, but a team above roughly the 50-100M ARR band with multi-region operations often belongs on Marketo. We implement both platforms and have no license commission pushing either answer.

Frequently Asked Questions
Can we migrate from Marketo to HubSpot in under a month?
Only by cutting scope in ways that surface later. A lift of contacts and templates can land in 2-3 weeks, but scoring, lifecycle, and the Salesforce sync arrive broken or missing, and the ops team spends the next quarter rebuilding in production. If a contract deadline forces speed, migrate data and active programs first and schedule the rebuild phase immediately after cutover.
Do Marketo smart campaigns transfer to HubSpot workflows?
No. There is no importer that converts smart campaigns into HubSpot workflows; the logic models differ. Every active campaign is rebuilt by hand. That is why the audit phase counts active campaigns first: migrating dormant programs is wasted effort, and a typical instance stores far more programs than it actually runs.
What happens to lead scoring in the migration?
Scoring is rebuilt, not copied: Marketo scoring tokens and score-change campaigns do not map one-to-one onto HubSpot score properties. Treat it as an opportunity. Most inherited models reward form fills and stale behaviors; rebuild against current funnel definitions and validate both models in parallel on one cohort before switching routing. Our lead scoring guide covers the rebuild itself.
