[QUOTE="MacInWin, post: 1872860, member: 396914"] Small nitpick. But maybe important. What Big Sur can't do is for Time Machine to recognize a backup from a previous version of macOS. Big Sur, as an operating system, can see the backup and can even use it for Migration Assistant if you wish. And that works for both Mojave and Catalina. But TM in Big Sur won't recognize a TM backup from Mojave or Catalina because they are different version of macOS. So you would need to create a new Big Sur TM backup from scratch. You can put it on that same drive without necessarily erasing the other, but that might confuse YOU (It won't confuse Time Machine). The same logic applies to your Time Capsule. The one difference is the TC backup is in a different format (sparsebundle), which is used to make backups over LANs to reduce the total data to be move. (Sparsebundles are lightly compressed to save that space.) [/QUOTE]
