Preparing for Tenant Rename

Before you initiate the tenant rename process, there are several critical preparatory steps to consider:

• Confirm Site Count: Utilize the SharePoint admin center or PowerShell scripts to verify your total site count prior to scheduling renaming activities.

• Licensing Needs: If your tenant exceeds 10,000 sites, Secure Advanced Management (SAM) licenses are necessary for each user in your organization.

• Understand Limitations: Be aware of limitations, such as hub site constraints, incompatibility with vanity domains, and potential third-party integration issues.

• Communication Strategy: It’s essential to inform site owners about impending changes using available public documentation.

• Validate Dependencies: Ensure that custom scripts, PowerShell automations, and any integrations still function with the updated domain name.
