Decision: Option 1: Workarounds Without Synchronization

Decision made by: IT Steering Committee

Date:   

Online Meeting: MS Programme IT SteerCo (organized by R. Clerc)

Issue

During the migration from Google Workspace to Microsoft 365, users are split between two calendar systems, making it impossible to view each other's availability across platforms. This lack of calendar visibility leads to scheduling difficulties and increases the risk of double bookings during the coexistence period.

Assumptions

Calendar Availability Challenges During Migration

...

Typical Coexistence Duration:
This dual-platform situation can last up to three weeks, depending on migration waves.

Options Considered

Option 1: Workarounds Without Synchronization

...

  • Security & Compliance: Ensure any 3rd party tool complies with company policies and data privacy regulations (SIP Validation required)
  • Temporary Need: The synchronization is only required during the migration window (3 weeks).
  • Estimated setup time: up to 6-8 weeks
  • Technical Complexity: Integration and support may require IT resources.
  • Cost: Evaluate licensing and support costs versus the productivity gains (only 1 RFP ~100k euro)
