The CRE Team's Guide to CRM Migration (Without Losing Your Data)

Step 1: Audit Your Current Data

Before you export anything, understand what you have. How many contacts? How many properties? How many active deals? What custom fields are you using? What data is in the CRM versus scattered in spreadsheets, emails, and team members' heads?

Create a simple inventory: Contacts (count, key fields), Properties (count, key fields), Deals/Opportunities (count, stages), Activities (calls, emails, notes — if exportable), Custom fields (list them all). This audit usually takes 1–2 hours and gives you a clear picture of what needs to move.

Step 2: Clean Before You Move

Migration is the perfect time to clean your data. Deduplicate contacts. Archive closed/lost deals you don't need. Remove test records. Update outdated contact information. Fix inconsistent formatting (company names, addresses).

Think of it like moving apartments — you don't pack the junk drawer. Cleaning before migration means your new system starts clean, which improves adoption and data quality from day one.

Step 3: Export from Your Current CRM

Most CRMs allow CSV export of contacts, companies, and deals. Export each object type as a separate CSV file. Make sure to export all custom fields, not just the default fields. If your CRM has activity/note export, grab that too — activity history is often the most valuable data, and the hardest to recreate.

Pro tip: Export in small batches if your CRM times out on large exports. And always download a backup before you start any migration work.

Step 4: Map Your Fields

Before importing into your new CRM, map your old fields to new fields. Some will map 1:1 (email → email, company → company). Others will need translation — Salesforce's 'Account' might map to Relio's 'Company', for example. Custom fields may need to be created in your new system first.

Relio's import tool includes a field mapping step where you can match your CSV columns to Relio fields, create new custom fields on the fly, and preview the import before committing. Most teams complete field mapping in 15–30 minutes.

Step 5: Import and Verify

Import your contacts first, then properties, then deals (since deals reference both contacts and properties). After each import, spot-check 10–20 records to make sure fields mapped correctly, relationships are intact, and no data was lost or truncated.

Common issues to watch for: date format mismatches (MM/DD/YYYY vs. YYYY-MM-DD), character encoding problems with special characters, and empty required fields. These are almost always fixable with a quick CSV edit and re-import.

Step 6: Bring the Team Along

Data migration is the technical part. Team migration is the human part — and it's often more important. A few things that help: involve 1–2 team members in the migration process so they feel ownership. Set a clear cutover date ('after Friday, all new data goes in Relio'). Keep the old system read-only for 30 days so people can reference it.

Most teams migrating to a purpose-built CRM like Relio report that adoption is faster than expected, because the new tool actually matches their workflow. You're not asking people to learn a complex system — you're giving them a tool that works the way they already think.

How Long Does It Take?

For a typical CRE team (500–5,000 contacts, 100–1,000 properties, 20–100 active deals), migration to Relio takes less than a day. The export and import process is usually 2–4 hours. Verification takes another hour or two. The rest is communicating the change to your team.

Compare that to the original CRM implementation, which probably took months. Migration is a one-time investment of a few hours that pays off every day afterward.
