Migrating off HubSpot without losing your pipeline data: a 30-day plan

We've migrated roughly 35 clients off HubSpot in the last three years. The migrations break at exactly two places: pipeline history and email deliverability. Almost everything else is straightforward.

This is the playbook we use, compressed to 30 days.

Day 0: The honest scoping conversation

Before we touch anything, we map four things:

1. What HubSpot is actually being used for. Most operators we audit are using 20% of HubSpot at most. Marketing emails, contact records, and one or two automations. The rest is paying-for-the-tier-you-need-to-get-the-feature-you-use.
2. What custom objects, custom properties, and historical data exist. Anything bespoke needs a target in the new system before migration day.
3. Email sender reputation history. What domain are you sending from? When was the last reputation incident?
4. Integrations downstream of HubSpot. Salesforce sync, Zapier flows, Slack notifications. Each one is a hand-off.

If you can't get clean answers to these in the first week, you're not ready. Slip the 30 days; do this work anyway.

Days 1–7: Build the new home

Set up the destination — in our case, the Revenue Engine's CRM and automation layer; for other migrations, it could be Salesforce, ActiveCampaign, or a custom stack.

Specifically:

• All custom HubSpot properties → fields in the new system, with type compatibility validated.
• All HubSpot lifecycle stages → corresponding stages in the new system.
• All HubSpot lists → segments in the new system, recreated from the underlying filter logic, not as static exports.
• Test contact created in HubSpot, migrated by hand, verified end-to-end in the new stack.

If a property has no clear destination, you don't migrate it. You document it as "intentionally dropped" with the operator's signoff.

Days 8–14: Email deliverability prep

This is the part operators skip and regret.

You cannot just point a new email-sending tool at your domain and start blasting. The new tool's IPs have a different reputation than HubSpot's. You will land in spam.

The 7-day prep:

• DNS records. Set up SPF, DKIM, and DMARC for the new sending platform. Validate with mxtoolbox or equivalent. Do not skip DMARC.
• Sender warm-up. Start the new platform sending to a small, highly-engaged subset of your list (top 5% by recent engagement) for 7 days. Volumes ramp daily. This is non-negotiable.
• Parallel send for one week. Critical campaigns continue going through HubSpot during warm-up. Operational emails (transactional, password resets) can move immediately.

If you skip this, your domain gets a deliverability hit you'll spend three months recovering from.

Days 15–21: Pipeline migration

Pipeline data is the one HubSpot export that almost never works clean.

The reason: HubSpot stores pipeline stage history as a series of property change events, not as a structured timeline. Most exports collapse this to "current stage only," and you lose the velocity, conversion, and time-in-stage data your sales org has been making decisions on for years.

The playbook:

1. Export the property change history for each deal record, not just the deals table. This is a separate API call.
2. Replay the property changes in the new system, in order, with original timestamps. This is engineering work; budget a few days of it.
3. Validate stage conversion rates and time-in-stage match HubSpot's reports for the last 12 months. If they don't, investigate before moving on.
4. Snapshot HubSpot's pipeline reports before cutover. Keep them. You will refer back.

Without this, your sales org will tell you in a month that "the new system isn't tracking deals right." It will be true.

Days 22–28: Integrations and automations

In order of risk:

• Inbound integrations (data flowing into HubSpot from somewhere else). Repoint the source. Validate.
• Outbound integrations (HubSpot pushing data to somewhere else). Rebuild or repoint. Validate downstream system has not silently dropped data.
• Marketing automations. Rebuild from scratch in the new system. Don't try to "migrate" them — the underlying primitives are different. Cleaner to redesign.
• Forms. Repoint form submissions to the new endpoint. Test from staging, then from production.

Day 29: Cutover dry run

Full simulation. Send a test email from the new system to your warm-up cohort. Submit a form. Push a contact through the pipeline. Verify the data lands where it should.

If anything breaks, slip the cutover by a week. Cost of slipping: low. Cost of cutting over broken: high.

Day 30: Cutover

Sunset HubSpot's marketing-sending in this order: warm-up cohort, full marketing list, transactional, integrations, finally the contracted seat reduction. Do not cancel HubSpot itself for at least 30 days post-cutover — you will need to query historical data.

What you save

For most operators we migrate off HubSpot, the math works out to roughly 60-75% of the previous monthly cost (HubSpot Pro/Enterprise tiers run $800-3,500+/month for the configurations operators actually buy). The bigger win is consolidation — most clients we move off HubSpot also retire 2-4 adjacent tools in the same engagement.

If you're considering a HubSpot migration, book a scoping call. We've done it enough times to be useful in the first 30 minutes.
