This module should have a system requirements area as you can't migrate from anything earlier than v4.4.
So anyone wishing to go from 4.1.10 for example, will need to upgrade to 4.1.12 and then again to 4.5.0 then install a fresh X-Cart v4.5.0 store with the upgraded database. You can also upgrade the fresh X-Cart installation to a newer version (for example 4.5.0 -> 4.6.0 -> 4.7.0 -> 4.7.7).
Its not "a few minutes" process.
Good luck!
