Moving to a new document management system is a chance to fix years of accumulated mess. It is also a risk. Firms that migrate everything as is carry over duplicate files, dead matters, inconsistent naming and permissions that nobody understands. The new system looks modern, and then inherits the same confusion.
A few weeks of cleanup before migration saves months of frustration afterward. This plan applies to moves among systems such as NetDocuments, iManage, SharePoint-based setups and file servers.
Start with an inventory
You cannot clean what you cannot see. Gather facts about the current environment:
- Where documents live: file servers, the current DMS, personal laptops, cloud drives, email attachments and removable media.
- Approximate volume by location and by age.
- The matter or client structure, and how consistently it is used.
- Who has access to what, including groups and exceptions.
- Integrations with email, practice management, billing and Microsoft Office.
Expect surprises. Many firms find client files in personal folders and shared drives that were never part of the official system.
Decide what should not move
Apply retention rules
Check your firm's file retention policy and applicable state bar guidance on client file retention, and confirm with your state bar and partners what must be preserved and for how long. Matters that have passed their retention period and have no hold may be candidates for secure destruction, but only after review and approval by responsible attorneys.
Honor legal holds
Never delete anything under a litigation hold or preservation obligation. Make a list of active holds before cleanup begins and share it with IT.
Remove obvious clutter
Duplicates, temporary files, system files, old installers and personal items can be removed or left behind. Tools can identify exact duplicates, though human review is wise for anything borderline.
Archive closed matters appropriately
Rather than migrating years of closed files into the active system, consider a lower-cost archive with controlled access and a clear retrieval process.
Fix structure and naming
A new system works best with consistent metadata. Decide on:
- Client and matter numbering. Align with your practice management and billing system.
- Document types and naming conventions. Keep them simple enough that people will follow them.
- Folder depth. Excessive nesting makes search harder and migration slower.
- Required fields. Decide what metadata attorneys must provide at save time.
Resist the urge to create an elaborate taxonomy. Simple and consistently applied beats elegant and ignored.
Clean up permissions
Migration is the best moment to correct access.
- Document who should have access to each client or practice area.
- Identify matters needing restrictions, such as ethical walls or sensitive clients.
- Replace individual permissions with role or group based access.
- Remove access for former employees and obsolete groups.
- Plan a periodic access review in the new system.
If you plan to use AI features in the new platform, permission hygiene becomes even more important, because AI search can reveal documents that were technically accessible but never noticed.
Plan the migration in stages
Pilot first
Move one practice group or a small set of matters. Test search, versioning, email filing, permissions and Office integration. Collect feedback.
Validate each wave
After each batch, compare counts and sample files between old and new systems. Confirm metadata, version history and file integrity. Keep a reconciliation log.
Keep the old system read-only
Retain the legacy system in read-only mode for a defined period so people can check anything missing. Back it up before decommissioning.
Schedule around deadlines
Avoid cutovers during trial weeks, filing deadlines or year-end. Communicate dates clearly.
Protect confidentiality during the move
- Use encrypted transfer methods and restrict migration accounts to the project.
- Ensure any migration vendor signs confidentiality terms consistent with your supervisory duties for nonlawyer assistance.
- Delete temporary staging copies and confirm in writing.
- Rotate migration credentials at completion.
Train and support
A new system fails when people do not adopt it. Provide short role-based training, one-page guides and floor support during the first weeks. Appoint a few champions among attorneys and paralegals who can answer quick questions.
After go-live
Review usage after thirty days. Look for documents still being saved elsewhere, search complaints and permission requests. Tune and reinforce. Add DMS backup and export procedures to your disaster recovery plan, since a cloud system is still something you need a recovery plan for.
Final thoughts
The cleanup is more valuable than the software. Counsel Cyber helps law firms plan migrations for document management and Microsoft 365, including inventory, permission review and secure transfer. If you are considering a move, a short assessment up front can shape the scope and prevent expensive surprises.
