Appendix A: Reduced RBAC model for O365 Migrations

This section outlines the minimal requirements for provisioning mailboxes in O365 and performing migration activities in the HCL Domino environment based on the security policies that exclude provisioning of a Global Admin account. Environmental issues could require adjustments to these rights and should always be validated by testing pilot migrations.

The minimum requirements listed below have not undergone formal QA testing. Adjustments might be required for your environment.
