Do I need to zip the [MSFSX folder]\Captain Sim\757 folder, also, or are those the same in both versions?

I think it is a good idea to add the FSX\Captain_Sim\757 folder to the zip. There are some differences in there, and you might have edited the sound.ini file to help sort out some minor sound issues and it would save on redoing them. If you do revert to 4.4, install it then unzip your backup to overwrite everything and you are back where you are now.

Add the FSX\Captain_Sim\navigation folder too, especially if you subscribe to navigraph update, as they will be out of date after you install 4.6 and/or reinstall 4.4.
