Surviving a CRM Migration to HubSpot

Bapusaheb Patil

Nobody wakes up excited about a CRM migration. It’s one of those projects that sounds straightforward in the planning meeting and then slowly reveals itself to be a beast. I’ve led migrations from Salesforce, Pipedrive, Zoho, and a few custom-built systems that probably should have stayed custom-built.

Here’s what I’ve learned about doing it without losing your mind.

Rebuild Before You Import

This is the single most important principle. Do not try to replicate your old CRM inside HubSpot. You’ll end up importing every bad habit, orphaned field, and workaround your team built over the years.

Instead, start fresh:

  1. Define what your CRM needs to do for your team right now
  2. Map out your deal pipeline stages from scratch
  3. Decide which properties you actually need (spoiler: it’s fewer than you think)
  4. Build your automation logic in HubSpot’s workflow editor before touching any data

Then, and only then, import your data into this clean structure.

The Data Cleanup Nobody Wants to Do

Roughly 70% of migration issues come from poor data quality. I know that’s a painful number, but I’ve seen it play out over and over again.

Before you export anything from your old CRM:

  • Deduplicate. Merge duplicate contacts and companies in your source system first. It’s way easier to clean data before it moves than after.
  • Audit your fields. Export a list of all custom fields. I guarantee at least a third of them are unused, outdated, or redundant. Don’t migrate garbage.
  • Standardize values. If your “Industry” field has 47 variations of “Software,” fix that before import. HubSpot dropdown properties will thank you.
  • Flag stale records. Contacts who haven’t engaged in over a year? Deals stuck in “Negotiation” since 2023? Leave them behind or archive them separately.

Mapping Fields: Harder Than It Sounds

Field mapping is where things get tedious. Your old CRM’s “Account Type” might map to HubSpot’s “Company Type,” or it might not exist at all. Some fields need to be split, others combined.

My approach:

  1. Export all fields from the source CRM with sample data
  2. Create a spreadsheet with three columns: Source Field, HubSpot Field, Notes
  3. Go through every field with someone from sales and someone from marketing
  4. Mark each field as “Migrate,” “Transform,” or “Drop”

The “Transform” category is where the real work lives. Date formats, multi-select values, currency fields, custom objects; they all need careful handling.

The Test Import

Never do a full import on the first try. Just don’t.

Run a test import with a small batch (50 to 100 records) and verify:

  • Do all field values land in the right properties?
  • Are associations intact (contacts linked to companies, deals linked to contacts)?
  • Do lifecycle stages map correctly?
  • Are any values truncated or malformed?

Fix everything the test reveals, then run it again. I usually do two or three test rounds before the full migration.

Timing and Cutover

Pick a migration window that minimizes disruption. For most teams, this means a weekend or a holiday period when deal activity is low.

The cutover plan should look like this:

  1. Friday evening: Final data export from old CRM. No new data entry after this point.
  2. Saturday: Run the full import into HubSpot. Verify record counts and spot-check data.
  3. Sunday: Configure any remaining automations, test email sends, verify integrations.
  4. Monday morning: Team starts working in HubSpot. Old CRM goes read-only.

Keep the old CRM accessible in read-only mode for at least 90 days. People will need to reference old notes, attachments, and activity history that might not have migrated perfectly.

Don’t Enable Automation on Day One

This is the mistake I see most often. Teams get excited, flip on all their workflows immediately, and suddenly hundreds of contacts are getting emails they shouldn’t be getting, deals are being reassigned, and lifecycle stages are changing in bulk.

Keep all workflows in draft mode for the first week. Let the data settle. Manually verify that key records look correct. Then enable workflows one at a time, starting with the least impactful ones.

Training Is Not Optional

You can build the cleanest HubSpot portal in the world, and it won’t matter if your team doesn’t know how to use it. Budget real time for training:

  • Sales team: How to log activities, manage deals, use the mobile app
  • Marketing team: How to build lists, create emails, read reports
  • Ops team: How to manage properties, troubleshoot workflows, run imports

Record these sessions. New hires six months from now will thank you.

The First 30 Days

After go-live, keep a close eye on:

  • Data entry quality. Are people filling in required fields or finding workarounds?
  • Pipeline accuracy. Are deals in the right stages with realistic close dates?
  • Adoption metrics. Who’s logging in daily? Who’s not using HubSpot at all?

The first month sets the tone. If bad habits form early, they’re incredibly hard to break later. Stay hands-on, answer questions quickly, and make small adjustments as your team settles in.

A clean migration isn’t just about moving data. It’s about giving your team a fresh start with a system they actually want to use.
