Hi Paul!
Migrating a 1C application to another domain is not a complicated task. Unfortunately, I haven’t worked with the “Quest Migrator Pro” solution myself, but if it supports migrating SQL databases, that should be sufficient.
You should pay attention to the following points:
How is authentication currently configured in the 1C application? Is it simple username/password authentication, or is domain-based authentication being used?
When migrating the 1C application to another domain, you will most likely need to update your 1C license, as the license is “bound” to a specific server.
Otherwise, the process is straightforward: migrate the SQL database, install the 1C server in the new environment, configure the database connection in the server console, and, if required, update the license using additional PIN codes.
