Many firms still run an on-premises file server in a closet, along with a legacy document system and maybe an old accounting application. These systems age, the hardware fails, and remote work exposes their limits. Moving to cloud-based tools such as Microsoft 365, a cloud document management platform, and cloud practice management is a common next step.
Done well, migration improves access, security and resilience. Done carelessly, it loses documents, breaks workflows and frustrates attorneys. Here is a roadmap.
Phase 1: Assess
Inventory what you have
List every server, application, shared drive, database and integration. Note who uses each and how. Include things that are easy to forget: scanners that save to a folder, accounting software, practice-specific tools, door access systems, and line-of-business applications.
Understand the data
- How much data is there, and how much of it is current?
- Which matters are active, closed and archived?
- Are there retention obligations for closed files?
- Where is sensitive data stored, including client files, personal information and trust records?
Identify what cannot move
Some legacy applications cannot run in the cloud without modification. Decide whether to replace them, host them in a secure virtual environment, or keep a small on-site footprint.
Phase 2: Plan
Choose the target platforms
Decide where each type of data will live: email and collaboration, files and documents, practice management, billing and accounting. Evaluate with your attorneys, not just IT.
Design the security model
Set this up before moving data:
- MFA and conditional access for every user
- Role-based permissions mapped to your matter and practice group structure
- Data loss prevention and sharing rules
- Device management for laptops and phones
- Logging and alerting
Cloud misconfiguration is a leading cause of exposure, so default settings should not be accepted blindly. ABA Model Rule 1.6(c) and Formal Opinion 477R both relate to reasonable safeguards for client information, and Formal Opinion 498 addresses virtual practice.
Plan backup and recovery
Cloud vendors keep their services running, but they do not always protect against accidental deletion, ransomware or malicious insiders. Plan an independent backup of Microsoft 365 and any critical platform, and define recovery goals.
Build a schedule and communication plan
Choose a cutover window that avoids filing deadlines and month-end billing. Tell staff what is changing, when, and what to do on day one.
Phase 3: Prepare Data
Cleanup before migration pays for itself.
- Delete duplicates and obsolete files, following retention policies
- Standardize client and matter naming
- Fix very long file paths and unsupported characters, which can cause failures
- Archive closed matters appropriately
- Identify files that nobody should have access to and fix permissions first
Phase 4: Pilot and Migrate
- Pilot with a small group that includes one attorney and one staff member
- Migrate in waves, such as by practice group, with a verification step after each
- Verify file counts, permissions and sample documents against the source
- Keep the old system read-only for a defined period as a safety net
- Train users with short sessions on the new tools before cutover
Phase 5: Cut Over and Stabilize
- Provide extra help desk coverage in the first two weeks
- Collect issues in one place and fix quickly
- Confirm that scanners, printers, mobile devices and integrations work
- Check that backups are running and perform a test restore
Phase 6: Decommission Safely
When confidence is high:
- Take a final verified backup of the old server and store it securely
- Wipe or physically destroy drives in line with your media disposal policy, with a certificate if a vendor does it
- Remove the old server from patching, monitoring and licensing
- Update your asset inventory and network documentation
- Close any firewall rules or remote access paths that served the old system
Common Pitfalls
- Underestimating how long data transfer takes over limited internet bandwidth
- Skipping permission cleanup and exposing more than intended
- Not planning for internet outages at the office
- Neglecting training
- Forgetting the printers and scanners
- Decommissioning the old system too soon
