Does anyone know how to export registered servers in Aqua Data Studio? Maybe there's some tricky method to do it by copying some .ini file or registry keys?
AD Studio server registrations are in [USER_HOME]/.datastudio/connections directory. You can copy your existing connections from one machine to another.
AquaFold's documentation about copying registrations from one computer to another is here:
