I want to update a project version, in this specific case, from UE 4.24 to UE 4.26. I have the project on Source Control (Perforce). I would of course make backups before upgrading, but if I was to upgrade versions, does Unreal and Perforce require me to check out and resubmit every file? Some files? Or just the project file.
The project is quite large and I’d like to avoid the network time if possible. Does opening the project in a different editor version change the files themselves?
