Impossible to move profiles to new domain profile

Hi All,
I’ve had two domains and recently I’m collapsed one of my domains, I’ve migrated everything to the correct new domain, however I cannot figure out how to make my old NextCloud profile my new NextCloud Profile.

I just want to make the original LDAP profile from my old domain be my current one. I feel it’s 100% impossible?

Thanks

@blizzz Any idea?

After many hours of searching until 4am Western Australia time, I found an app on the NextCloud store called User Migration, However, I doesn’t seem to want to backup anything? even though it says there is 13gb on the profile
