Hello. (Moved this post from another community)
Azure Active Directory Premium P1 is currently on the list of SKUs "enabled for migration but need to be manually migrated". Can you explain what this means?
Also, it says that this is just a sample of the popular products that are enabled but need manual migration. How do we tell if other SKUs not listed here need to be manually migrated?
Right now, in the case of AAD Premium P1, the migration tool looks like it's enabled - what happens if we try to proceed using the migration tool? Will there be an error message indicating that a new subscription needs to be purchased first and manually migrated?
Thank you in advance.
