I fully agree. And i am missing some information from the OP: Was the 500 GB drive UEFI already? Will both drives live on the same computer ever? If the answers would be yes to 1 and no to second, that would allow reusing the UUID's, which can be manipulated (on the new disk) with sgdisk. But of course, since that involves some kind of "hacking", i recommend to create some understanding along the disk format necessities for UEFI booting first, like from https://www.rodsbooks.com/ pages. My goal would be to manipulate the target to come very close to the source, except for the partitioning/fs layout, in order to prepare for a successful rsync for ALL (except swap, but including ESP) partitions. mkswap has a -U switch too. :-)
