A global consultancy migrated from on-prem Exchange and file shares to Microsoft 365 with no user-visible downtime and zero support tickets on cutover day.
Ardent had 900 employees across three continents on ageing Exchange 2016 and a mesh of DFS file shares. Previous migration attempts had stalled due to mailbox size, legal hold requirements, and executive resistance after a bad experience with another vendor.
AURA Technologies ran a phased hybrid migration with pilot cohorts, executive white-glove support, and a purpose-built Teams governance model. Legal holds were preserved via retention policies before mailbox move. SharePoint replaced DFS with clear IA and provisioning automation.
All 900 mailboxes migrated in six weekend windows with zero business-hour disruption. Go-live Monday generated zero support tickets. Storage costs dropped 38% and mobile productivity metrics rose within the first month.
“The Microsoft 365 migration was invisible to our 900 employees. Zero downtime, zero support tickets on go-live.”
