Before You Start: Pre-Migration Planning
Successful migrations begin weeks or months before any data moves. Start by auditing your current platform: document every workflow your team uses, identify all data types stored in the system (cases, contacts, documents, notes, time entries, billing records, communications), and catalog any integrations or automations you rely on. Set a realistic timeline — most firm migrations take four to eight weeks from planning to completion, though larger firms may need longer. Assign a dedicated project lead, ideally someone who understands both your current workflows and the capabilities of your new platform. Create a written migration plan that includes milestones, responsible parties, and a rollback strategy in case of unexpected issues.
Choosing Your Migration Window
Timing your migration poorly can create serious risks for your practice. Avoid migrating during periods when you have approaching trial dates, statute of limitations deadlines, or other time-sensitive obligations that require uninterrupted access to your case data. Many firms find that slower practice periods — often late December through early January, or mid-summer — provide the best migration windows. If your firm handles a high volume of cases, consider migrating in phases rather than all at once: move closed or archived cases first, then active cases. Build in buffer time for unexpected delays. A migration that takes two weeks longer than planned is far better than one that's rushed and results in data issues during a critical case deadline.
Data Inventory and Cleanup
Migration is the ideal time to clean house. Run a complete inventory of your current data and categorize it into three buckets: data that must migrate to the new platform, data that should be archived but doesn't need to be actively accessible, and data that can be deleted. Look for duplicate records, outdated contact information, cases that were never properly closed, and documents that no longer serve a purpose. Cleaning up before migration rather than after saves significant time and money — especially if your new vendor charges based on data volume. Export a complete backup of everything from your current platform before you begin any cleanup, so you have a safety net if something is accidentally deleted.
Migration Cost Comparison by Vendor
Migration costs vary enormously across vendors and can significantly impact your first-year budget. inTrial Manage offers free data migration and dedicated onboarding support, handling the technical heavy lifting for your firm at no additional cost. Clio also provides free migration assistance, making it financially easy to switch. CasePeer typically charges between $1,000 and $8,000 for migration services depending on the volume and complexity of your data. Filevine migration and implementation fees range from $1,250 to $25,000 or more, with costs scaling based on firm size and customization requirements. Litify, built on the Salesforce platform, has the highest migration costs in the market — implementations commonly run $10,000 to $250,000+ including data migration, platform customization, and training. Always get a written quote for migration costs before signing a contract with any vendor.
The Migration Process: What to Expect
A typical migration follows a predictable sequence. First, your new vendor will request a data export from your current platform and review it to create a data mapping plan — determining how fields, categories, and relationships in the old system correspond to the new one. Next comes a test migration, where a subset of your data is imported and verified for accuracy. After the test migration is validated, the full migration is performed. Most vendors recommend a parallel running period of two to four weeks where both systems are active simultaneously. During this period, new work is entered into the new system while the old system remains available for reference. Finally, the old system is decommissioned once your team confirms that all critical data has transferred correctly.
Training Your Team
Under-investing in training is the most common reason migrations fail to deliver expected benefits. Even if your new platform is more intuitive than the old one, your team needs structured training to build new habits. Consider a phased approach: train a small group of power users first, then have those power users help train the rest of the firm. Schedule hands-on training sessions where team members perform their actual daily tasks in the new system, not just watch demonstrations. Create quick-reference guides for the most common workflows. Plan for a productivity dip during the first two to three weeks — this is normal and temporary. Firms that invest in thorough training consistently report faster adoption and higher satisfaction with their new platform.
Post-Migration Verification
After the migration is complete, systematic verification is essential. Spot-check a representative sample of active cases to confirm that all data fields transferred correctly — case details, contact information, documents, notes, and calendar entries. Verify that document links work and files open properly. Test critical workflows end-to-end: opening a new case, generating a document, sending a client communication, tracking a deadline. Confirm that any integrations with external tools (email, calendar, accounting) are functioning. Check that user permissions and access controls are set correctly in the new system. Document any discrepancies and work with your new vendor to resolve them before decommissioning the old platform.
Common Migration Mistakes to Avoid
The most frequent migration mistakes are avoidable with proper planning. Rushing the timeline is number one — firms that try to complete a migration in a week almost always encounter problems that a four-to-six-week timeline would have prevented. Skipping data cleanup before migration means importing years of messy, duplicate data into your clean new system. Not testing with real cases during the parallel period leaves issues undiscovered until they cause problems in live matters. Failing to get buy-in from the full team leads to resistance and workarounds that undermine the new system. Neglecting to verify data integrity after migration can mean discovering missing information months later when you need it for a case.
