We want to migrate from MSPControl 1.0 to SolidCP.
We have followed the migration guide, but are unable to login after following all steps (serveradmin password is incorrect).

We have set the cryptokey to be the same.

Resetting the serveradmin password through the installer doesn't work, since the installer doesn't "detect" our installation.
We have 80+ organizations and 200+ mailboxes in there, so manually recreating everything isn't an option for us, this will involve too much work.

What would be the proper way to reset the serveradmin password after the migration?
