Exchange Online Migration (from Microsoft Exchange on Premise)

Task

The customer was already using an on-premise Exchange Server 2012 with grown structures. As part of an outsourcing project, I accompanied the migration to Exchange Online as the main technical contact on the customer side.

Solution

• Requirements and risk analysis
• Preparation of the source environment for migration (Exchange upgrades, configuration ADSync, customization of user accounts)
• Creation and monitoring of migration batches
• Configuration of internal email proxy and corresponding transport configurations
• Consulting on backup solutions in the Office 365 environment
• Coordination of downstream service providers

Profile

• Industry: Pharmaceutical industry
• Period: 2020
• Technologies:
  • Exchange Online
  • Microsoft Exchange
  • PowerShell

The migration was carried out without any noticeable interruption to operations. While started as a hybrid setup, ultimately the local components could be eliminated after the introductory phase, reducing costs and sources of error.
