I’m considering updating from a 128GB to 512GB card. Normally, the procedure would to be create a disk image and restore it to the new card. I’m a bit skeptical of this process being this straightforward; in fact, I think this will simply break stuff for many apps.

I have several of my apps point to a folder on the card for data storage or backup, and the path includes what I believe is the serial number of the card – it’s an 8 character code of mostly digits and two upper score letters. This, I believe, will not carry over to the new card, therefore probably forcing me to format it and making me unable to access existing data. I can work with doing to connections all over, because it’s 10 apps at most that do automatic backups on the card, but I have previously had problems with Android devices forcing card formatting despite the correct file system. The thing I’m mostly scared about is YouTube Music encrypted library

Does anyone here have experience doing so?

    it’s an 8 character code of mostly digits and two upper score letters.

    That’s the UUID of the VFAT filesystem on the card, so if you clone the card and then resize the partition you’ll keep the same filesystem UUID on the new card.
