Rolling back in case of unsuccessfull migration from connect to forge

Hello everyone!

I have an existing app based on connect (the app is uploaded to the market) and I want to perform a migration from connect to forge.
As a guide I’m using this artcicle - Get help

We have already performed some migration tests witn new empty apps and they seem to be successfull.
But I still have a big concern that something will go wrong during the real migration.
I haven’t found any related information about rolling back such changes. So, the app will be based on connect again. Is it possible?
