Migrating a 14-partner Trafford law firm to fully cloud-based working in 11 weeks

"We expected pain. We got one weekend of mild inconvenience." — Office Manager

The situation

A 38-person Trafford law firm — established mid-1990s, full-service civil and family — was planning an office move scheduled for spring 2026. The new premises had no server room. The existing setup was a pair of ageing Windows Server 2019 boxes running Active Directory, an on-prem Exchange (yes, still), and a legal practice management system tied to a SQL Server in the corner of the comms cupboard.

The brief was straightforward in principle: be entirely cloud-based by move-day, no on-prem footprint, no compromises to client confidentiality, no extended downtime. The firm had four months. They came to us with eleven weeks left on the clock.

The plan

We built a four-stream parallel cutover:

1. Identity — Hybrid AD → Entra ID, conditional access from day one
2. Email — Exchange on-prem → Exchange Online with full mailbox migration and journaling for SRA compliance
3. Files — File server → SharePoint with matter-based document libraries and retention labels
4. Practice management — Vendor-hosted cloud version of their existing PMS, with data migrated and validated before cutover

The risks we managed

• Client confidentiality and SRA compliance — every step was documented against SRA Code of Conduct rule 6 (confidentiality). Compliance Protect setup included audit logging on every privileged action
• Email continuity — partners receive court correspondence in real time. We ran a parallel-flow period for 14 days where mail flowed to both old and new systems
• Practice management data — the firm had 22 years of matter history in the SQL database. We ran three full migration dry-runs before the live cut, with validation against record counts, file hashes, and a stratified random sample of 200 matters checked manually by paralegals

The cutover

The live cutover ran on a Saturday in February. Total downtime: 4 hours 20 minutes for email, 6 hours for files, 8 hours for the practice management system.

Monday morning, all 38 staff logged in via Entra ID, opened Outlook, opened SharePoint, opened the new PMS, and got on with the day. Zero data loss against the validation manifest. Zero matters lost.

The numbers

Metric	Result
Project window	11 weeks (originally scoped 16)
Total user-facing downtime	1 day (Saturday)
Data validation pass rate	100% (200/200 sample matters)
User support tickets in week 1	23 (mostly password/MFA setup)
User support tickets by week 4	6
Office move readiness	Day-zero ready
On-prem server room footprint	Eliminated

Twelve months on

The firm has been fully cloud-based for over a year now. The office move went ahead in March 2026 — the comms cupboard at the new site holds a single network rack, no servers. They've added two new partners since the move. Onboarding each took 22 minutes of IT time.

"We were nervous about cloud. We're now wondering why we didn't do it five years ago. Inology made it boring, in the best possible way."

Considering a similar move?

If you're planning a relocation, a server refresh, or just want out of the on-prem maintenance cycle — we're happy to scope a fixed-price migration. We'll be honest about whether the timeline is realistic and what the genuine risks are. Drop us a line.
