...and reformatting to APFS for my new MacBook Pro M3 Max.

It's, as mentioned 2TB, a Samsung T7 - and everything, literally everything I don't want on the local machine's storage resides on it. From my Creative Suite (Adobe) scratch disc files to sound effects, Logic beds, effects and 'sounds' instruments, as well as Dropbox/OneDrive sync, iTunes library (over a 100,000 songs) 150-200GB of pics and video, etc.

I bought the T9 4TB & I formatted it to APFS, was planning to backup my media library which Ive done - and have ample room to back up the entirety of the T-7 (older 2TB external) - and am thinking I should just back it up (takes minutes on these guys) and reformat the T7 to APFS then putting the files and folders back to the T-7 in the same structure as before the format.

Hope this makes sense

My question is simple.

Will I need to go back through each app and reset their cache folders, sounds, pics, DropBox and OneDrive syncing etc? Or will Adobe and Windows and other backup apps recognize the file path after reformatting?

It's simple to back up and reformat, then resend the info back to the original drive - but the time consumer is re-linking all the app's different scratch and caches, project or sound and stills/motion, titling, even transitions, titling etc can take up plenty of space unnecessarily on the laptop itself (I got 2TB, and refuse to spend more on storage with Thunderbolt drives becoming more plentiful, etc - and I've got plenty of room with 2TB for my apps and OS and it's idea of optimizing storage (iCloud, Photos, etc ;))

I looked for an answer to this specifically but only found questions on how to not lose data reformatting etc - which I know will leave me with a blank SSD formatted as APFS when done - so I'm only wondering about how the different non-Apple apps - or even the FCPs and Logics will act with their libraries on the external drive currently formatted as macOS Journaled or OSX Journaled, after I make it an APFS drive with identical file structure

Giving the new APFS volume the same name should be enough, without having to clone the UUID.

You can easily try this by setting up the second backup of your T7 (please tell me there won't be a moment in time where a single drive failure will lead to data loss) exactly as you will the T7 after restoring. Then check whether everything works with that backup before erasing the T7.
