Migrate LDAP-backend users to AD

Hello community!

Right now I’m using an LDAP backend to authenticate users against my Nextcloud (10.0) instance.
The association (ldapExpertUUIDUserAttr) is made by the uid. I’ve migrated the users to my new and shiny AD.

They currently exist in both backends. I have yet to

Now to my question:
Is it possible to switch the the backend from the LDAP server to the DC without loosing the old user profiles (files, shares, appsettings, …)?
If not, what would be the best practice to restore the user profiles to their AD counterparts?

Best regards

Maybe it will be possible with editing ldap_user_mapping table from database?
