What actually happens during a migration
A migration runs in four phases: audit, mapping, build, and cutover. First we pull a full inventory of what's in your current system — contacts, pipelines, forms, calendars, automations, and every integration touching them. That audit is what turns a guess into a real timeline.
From there we map old fields and stages to their GoHighLevel equivalents, rebuild the automations that don't transfer as-is, and test everything in a sandbox before it goes live. Cutover happens on a scheduled date so there's no gap where leads fall through. Most businesses see 2 to 4 weeks start to finish; more integrations or custom logic pushes toward the longer end.
What moves over, and what doesn't
Contacts, tags, pipelines, and standard automations transfer directly with no rebuild needed.
Custom funnels, calendars tied to specific staff, and multi-step workflows need to be rebuilt and tested, not copied.
Third-party integrations, A2P phone number registration, and anything scraped from an old system's API can break silently if rushed.
Where migrations go wrong
Most self-migrations don't fail on the easy parts — they fail on the pieces nobody accounts for up front: A2P phone registration that stalls texting for weeks, integrations that quietly stop syncing, or a cutover done live with no rollback plan. Those problems don't show up on day one. They show up a month later as missed leads and duplicate records.
A done-for-you migration removes that risk: we run the audit, do the rebuild, test in parallel with your live system, and only cut over once everything checks out clean.
