How do you migrate to GoHighLevel without losing leads?
Migrate in four phases: export and clean contacts, port or forward phone numbers with A2P registration done in advance, run both systems in parallel for two weeks with every new lead landing in GoHighLevel, then switch off the old tool once reports match. Done this way, no lead, number or review request is lost.
What causes leads to get lost in a CRM migration?
Leads are lost in migrations for three reasons: a form or ad integration still points at the old system after it is cancelled, a phone number stops texting because carrier registration was not moved, and nobody is watching the old inbox during the handover. None of these are technical problems; they are sequencing problems.
The fix is to migrate in phases and never switch anything off until the new system has proven it receives everything. Ownership matters here too: set up the new account in your own name from day one, as explained in our data ownership guide.
How do you prepare before moving anything?
Inventory every lead source
Website forms, chat widget, Meta and Google lead forms, Google Business Profile calls, call tracking numbers, booking links, referral partners. Write the list; it becomes the cutover checklist.
Export and clean contacts
CSV with name, phone, email, tags, pipeline stage, source and consent date. Remove duplicates and dead numbers before import, not after.
Register A2P 10DLC on the new account
Brand and campaign registration takes days to weeks. Start it first so texting works the day the number arrives.
Document the automations that produce bookings
Screenshot each workflow. Keep the ones that book appointments; drop the rest.
How do you move numbers and contacts?
Submit the port request
Provide the carrier bill and authorisation. Keep the old service live until the port completes. Expect one to four weeks.
Forward in the meantime
Forward the old number to a temporary GoHighLevel number so the AI receptionist and missed-call text-back start working immediately.
Import contacts with tags and consent
Map source and consent fields so TCPA records survive. Tag everyone “migrated” for later reporting.
Rebuild the four core workflows
New-lead follow-up, missed-call text-back, appointment reminders, review requests. Test each with a real phone.
How do you run in parallel and cut over?
Point every lead source at GoHighLevel
Change form endpoints, ad-form integrations and booking links one by one, ticking the inventory list.
Run both systems for two weeks
Compare daily: leads received, texts delivered, appointments booked. Investigate any gap the same day.
Switch off the old automations first, then the tool
Disable old workflows to stop duplicate texts, keep read-only access for 90 days, then cancel.
Report cost per booked appointment by source
The first clean report from the new system is your baseline for everything that follows.
What must be true before you cancel the old CRM?
| Check | How to confirm |
|---|---|
| All lead sources deliver into GoHighLevel | Submit a test through every form, ad and link on the inventory |
| Number porting complete and texting delivers | Send a text from the ported number to a mobile on each major carrier |
| A2P 10DLC brand and campaign approved | Status shows approved in the sub-account |
| Contacts, tags and consent imported | Record count matches the export; spot-check 20 contacts |
| Core workflows live and tested | Each has produced at least one real booking |
| Two weeks of matching lead counts | Daily comparison shows no missing leads |
| Old automations disabled | No duplicate reminders received by test contacts |
| Read-only access to the old system retained | Login works; export saved to your own storage |
Common questions about migrating to GoHighLevel
How long does a migration take?
Two to four weeks for a typical local business: one week of preparation, one to two weeks of parallel running, and a few days of cutover and cleanup. Number porting is usually the slowest step.
Will I lose my phone number?
Not if you port it correctly. Keep the old service active until the port completes, never cancel first. Register A2P 10DLC on the new account before the port so texting works on day one.
What about conversation history?
Most CRMs export contacts and notes but not full SMS threads. Export what you can, attach it as notes, and keep read-only access to the old system for 90 days.
Can I migrate from Jobber, HubSpot or ActiveCampaign?
Yes. Each exports CSV contacts with tags or lists. Our comparisons for HubSpot and ActiveCampaign explain what maps directly and what has to be rebuilt.
Do I have to rebuild all my automations?
Yes, but it is an opportunity. Most businesses carry five to ten workflows that no longer make sense. Rebuild the ones that produce bookings first: missed-call text-back, new-lead follow-up, reminders, reviews.
What is the most common mistake?
Cancelling the old tool before the new one is proven. Run both for at least two weeks and compare lead counts, booked appointments and texts delivered.
What is related to GoHighLevel migration?
No auto-renew. You own everything. Paid on booked appointments.
Every system we build sits in your own account, on your own numbers and domain. If you stop working with us, nothing switches off and nothing has to be migrated.
