We recently moved all our users from Tenant1 to Tenant2. And Sharepoint, Teams and onedrive data was copied from Tenant1 to Teanant2.

I need to monitor if there is still some activity on Tenant1 (For Eg: Some users still authenticating against this tenant, etc).

  • What are the things I should monitor for?
  • Are there some other things I need to worry about to copy over from Tenant1
  • There is a retention policy on Tenant1 which retains data for x years. So there will be some data like deleted files sitting in the preservation hold library. What is the best way to copy that data across to Tenant2?

    Hi curious7

    Check the following conditions before decommisioning tenant :

    • You've paid all outstanding invoices and amounts due or overdue.
    • No users are in the Azure AD tenant, except one global administrator who will delete the organization. You must delete any other users before you can delete the organization.
    • If users are synchronized from on-premises, turn off the sync first. You must delete the users in the cloud organization by using the Azure portal or Azure PowerShell cmdlets.
    • No applications are in the organization. You must remove any applications before you can delete the organization.
    • No multifactor authentication providers are linked to the organization.
    • No subscriptions for any Microsoft Online Services offerings (such as Azure, Microsoft 365, or Azure AD Premium) are associated with the organization.

    You can check the Sign in logs if there is any activity that will give you a view if the tenant is in use.

    Follow the below link this has everything you need to go through before decommisioning a tenant :
