- The transition had to avoid disruption to financial operations
💡The approach
Advania delivered the project using a phased methodology:
Plan

- Exchange migration readiness planning
Prepare
- Infrastructure preparation tasks
- Testing and remediation planning
- Migration training for internal support teams
Migrate
- Pilot migrations to validate approach
- Full mailbox migration by region
- Decommissioning of Exchange 2010 infrastructure
☑️The outcome
- Consolidated messaging infrastructure across merged organisations
- Improved system performance and stability
- Platform prepared for future cloud adoption
