Hi,
I am going to perform o365 tenant to tenant migration. I have some shared mailboxes which I want to migrate from one tenant to another tenant. Should I create any identity in destination Azure AD for the shared mailboxes like user etc before migration? OR do not need to create any thing in Azure AD. It will create automatically during the migration.
Please answer me as soon as possible. thanks
Regards
