Key Takeaways:
- Start your data cleanup 3-6 months before migration to avoid the 83% of migrations that fail or exceed budgets
- Focus on five critical areas: client/matter data, financial records, trust accounts, document organization, and historical transactions
- Implement a systematic cleanup process using validation tools and team collaboration to ensure accuracy and compliance
Your law firm’s accounting data is like a filing cabinet that’s been accumulating papers for years. Some documents are pristine and perfectly organized. Others are coffee-stained, misfiled, or maybe shouldn’t even be there. Now imagine trying to move that entire cabinet to a new office without sorting it first.
That’s exactly what happens when law firms attempt to migrate accounting systems without proper data cleanup. The result? According to recent industry research, 83% of data migration projects fail or exceed budgets due to poor planning or lack of expertise. But here’s the good news: with the right preparation, your firm can join the successful 17%.
Why Data Cleanup Can Make or Break Your Migration
Think of data migration like moving to a new home. You wouldn’t pack garbage bags full of junk mail, broken appliances, and that exercise bike you never use. Yet many firms try to migrate years of uncleaned data, including duplicate client records, orphaned matters, and reconciliation nightmares that have been haunting their books since 2015.
The consequences of skipping cleanup are real and expensive:
Financial Impact: Failing to comply with regulatory requirements—like data protection or tax laws—can lead to penalties reaching up to $250,000 for each violation. That’s not counting the cost of fixing errors post-migration or the lost billable hours spent untangling data messes.
Operational Disruption: If migration is not carefully planned, your accounting systems can experience prolonged downtime, which disrupts daily business operations. This affects everything from processing invoices to managing payroll and handling client trust accounts.
Trust Account Compliance: For law firms, trust accounting errors aren’t just inconvenient—they’re career-threatening. Mishandling client funds remains one of the most common reasons for serious disciplinary action against lawyers.
The Five Critical Areas to Clean Before Migration
1. Client and Matter Data: Your Foundation
Your client and matter data forms the backbone of your entire accounting system. Start here, and everything else becomes easier.
What to Look For:
- Duplicate client entries (Yes, “Smith, John” and “John Smith” and “J. Smith Esq.” might all be the same person)
- Inactive clients who haven’t had matters in 5+ years
- Inconsistent naming conventions
- Missing or incorrect contact information
- Matters that were never properly closed
Action Steps:
- Run a duplicate detection report focusing on phone numbers and email addresses
- Standardize naming conventions (decide now: “LLC” or “L.L.C.”?)
- Archive inactive clients according to your retention policy
- Verify primary contact information for active clients
- Close matters that have been dormant for years
Pro Tip: Create a “Data Cleanup Committee” with representatives from accounting, IT, and your practice groups. Different people will spot different issues.
2. Financial Records: Follow the Money
Your financial data tells the story of your firm’s health. Make sure it’s telling the truth.
What to Look For:
- Unreconciled transactions from previous years
- Stale outstanding checks (anything over 6 months)
- Write-offs that were never properly processed
- Suspense accounts with unexplained balances
- Journal entries without proper documentation
Action Steps:
- Complete all bank reconciliations up to the current month
- Research and clear suspense account items
- Process write-offs according to firm policy
- Document any unusual transactions or adjustments
- Ensure your trial balance actually balances
The Hard Truth: If you can’t explain a transaction from 2019, you probably won’t be able to explain it after migration either. Deal with it now or delete it according to your retention policies. Consider outsourcing your accounting if your team is overwhelmed.
3. Trust Account Records: Handle with Extreme Care
Trust accounting errors can end careers. Period. This is where you need to be absolutely meticulous.
What to Look For:
- Client ledgers that don’t match trust account balances
- Unidentified deposits
- Stale-dated checks in trust
- Negative client trust balances (huge red flag!)
- Missing or incomplete three-way reconciliations
Action Steps:
- Perform a complete three-way reconciliation for every trust account
- Research and resolve any unidentified deposits
- Address negative balances immediately
- Ensure every penny in trust is assigned to a specific client/matter
- Document your reconciliation process for the new system
Remember: Most data conversions that involve legal accounts and practice management software will require some level of manual data transformation before the data migration can take place. Trust accounts require extra attention because the stakes are so high. Understanding IOLTA requirements and avoiding common trust accounting pitfalls is essential.
4. Document Organization: Digital Spring Cleaning
Your documents need structure, not chaos. A migration is the perfect time to implement better organization.
What to Look For:
- Documents saved in personal folders instead of matter folders
- Inconsistent file naming conventions
- Duplicate documents across multiple locations
- Outdated document retention compliance
- Missing metadata or indexing
Action Steps:
- Establish standardized folder structures
- Create and enforce file naming conventions
- Delete duplicates and outdated drafts
- Move documents from personal to matter folders
- Ensure proper metadata for searchability

5. Historical Transaction Data: Know What to Keep
Not all historical data is created equal. Some you need for compliance, some for reference, and some is just digital dust.
What to Keep:
- 7 years of financial records (most common requirement)
- All trust account records per your state’s requirements
- Active matter financial history
- Tax-related documentation
- Audit trails and compliance reports
What to Consider Archiving:
- Closed matters beyond retention requirements
- Inactive vendor records
- Old rate tables and fee structures
- Departed employee data (per HR policies)

Tools and Techniques for Efficient Cleanup
Leverage Technology
Modern legal accounting software includes validation tools. Use them. Run every report available to identify:
- Data integrity issues
- Compliance gaps
- Duplicate records
- Incomplete transactions
The Power of Parallel Running
Your data should run on both your old and new software for a few weeks, so that you can ensure everything has transitioned smoothly to the new software before you lose access to the old. This dual-running period is your safety net.
Document Everything
Create a “Data Cleanup Log” that tracks:
- What was changed
- Who made the change
- When it was changed
- Why it was changed
- Where the original data is backed up
This documentation becomes invaluable during migration and for future audits.
Common Pitfalls to Avoid
The “We’ll Fix It Later” Trap
If you wouldn’t serve a client dirty data, don’t serve it to your new system. Problems don’t get easier to fix after migration—they get harder and more expensive.
Underestimating Time Requirements
Even if you pad the quote and buffer in the time it will take to manage the migration, there are always surprises. Build in extra time for the unexpected, because the unexpected is actually expected in data migration.
Going It Alone
Your accounting team knows the books, but do they know data migration? Consider bringing in experts who’ve done this before. The cost of expertise is minimal compared to the cost of failure.
Ignoring State-Specific Requirements
Trust accounting rules vary by state. What works in California might get you disbarred in New York. Know your local IOLTA requirements before you start moving data.
The Payoff: Why Clean Data Matters
Clean data isn’t just about successful migration. It’s about transforming how your firm operates:
Improved Efficiency: Clean, standardized data means faster searches, accurate reports, and less time hunting for information.
Better Decision Making: When your data is accurate, your financial reports actually mean something. You can make strategic decisions based on facts, not fiction.
Enhanced Compliance: Clean trust accounts and proper documentation mean you sleep better at night, knowing you’re audit-ready.
Cost Savings: 70% of respondents indicated they use web-based services in the 2022 ABA Legal Technology Survey Report. Clean data makes the transition to modern, cost-effective cloud solutions smoother.
Moving Forward with Confidence
Data cleanup isn’t the exciting part of getting new legal accounting software. It’s not as fun as exploring new features or imagining streamlined workflows. But it’s the foundation everything else builds on.
Think of it this way: You’re not just cleaning up old data. You’re setting up your firm for years of efficient, compliant, and profitable operations. Every duplicate record you merge, every transaction you reconcile, and every document you organize is an investment in your firm’s future.
Start your cleanup process today. Your future self—and your accounting team—will thank you.
FAQ: Data Cleanup Before Migration
Q: How long should data cleanup take for a mid-sized law firm?
A: Plan for 3-6 months for a thorough cleanup. Firms with 20-50 attorneys typically need 3-4 months, while larger firms may need 6 months or more. The timeline depends on your data volume, current data quality, and available resources.
Q: Should we clean up all historical data or just recent years?
A: Focus on active data first, then apply your retention policies. Generally, clean up:
- All active client and matter data
- 7 years of financial records (or your state’s requirement)
- All trust account records
- Documents for active matters Archive or delete older data according to your firm’s retention policy and state requirements.
Q: Can we do data cleanup ourselves or should we hire consultants?
A: Many firms use a hybrid approach. Your internal team knows your data best and should lead the effort. However, migration consultants can provide valuable expertise on technical aspects and best practices. Consider consultants if you have limited IT resources or complex data structures.
Q: What’s the biggest mistake firms make during data cleanup?
A: Underestimating trust account complexity. Many firms discover reconciliation issues, unidentified deposits, or compliance problems during cleanup. Address these issues completely before migration—trust account errors can result in serious disciplinary action.
Q: How do we maintain data quality after cleanup?
A: Implement data governance policies before migration:
- Standardized data entry procedures
- Regular reconciliation schedules
- Periodic data quality audits
- Clear ownership of data maintenance
- Training for all users on data standards
