Hi,
We need to migrate Azure AD connect from a Forest to a new Forest while using the same O365 Tenant. There are several posts here and elsewhere explaining the steps and I was able to follow these steps in a Lab and migrate User accounts. It seems removing the Immutable ID is the key to not have duplicate accounts.

My question is how can I remove the Immutable ID of a Distribution Group? Is this possible? I found the Distribution group is duplicated when re-enabling Azure AD Connect Sync on the new Forest, which must be because of the Immutable ID. I know there are powershell commands to see and clear the Immutable ID for a O365 User account - is there a command to clear it for a Distribution Group?

Thank you All!
