Google Workspace migration for a professional services firm

Migrating ~45 users from a mixed Microsoft / legacy mail setup to Google Workspace with planned cutover and two weeks of hypercare.

Challenge

The firm had growing collaboration friction: shared drives were inconsistent, mailbox quotas caused weekly tickets, and partners wanted browser-first Docs without losing calendar reliability. A previous “DIY weekend cutover” attempt had been abandoned.

Approach

  1. Discovery of mailboxes, aliases, DNS and file shares
  2. Pilot with partners + finance + ops (8 users)
  3. Staged Drive migration and MFA rollout before MX change
  4. Friday evening MX cutover with Monday hypercare desk
  5. Leavers/joiners runbook handed to practice manager

Method aligned to our Workspace migration guide.

Results (anonymised)

  • ~15 minutes of inbound mail gap at cutover (planned MX TTL)
  • Zero lost mailboxes; aliases and shared inboxes remapped
  • ~40% fewer “where is that file?” tickets in the first month (internal count)
  • Partners adopted shared Drives for matter folders within two weeks

Metrics are client-reported / ticket-system counts with identifying details removed. Individual results vary.

Services used
