Legacy to Cloud:
The Support Cliff.

The client, a leading Petrochemical entity, was operating on Exchange Server 2007—a platform that had reached end-of-support. This posed significant security risks and lacked the modern collaboration features required for a distributed workforce.

Critical Constraints:

  • Uninterrupted 24/7 Operations
  • Historical Data Integrity (800+ Mailboxes)
  • Legacy AD Integration with Azure AD
