Hi, potentially you could 'keep' your old luks header and copy it over (backup+restore) to the new partition, if you plan on keeping masterkey, passwords, uuid. Is there a better way? Depends on what you call better? faster/safer? Imho your plan should be the safest version and that's probably what you want, esp. if part. 5 has enough space to hold what's on part 6 (So you would have your data twice just to make sure everythink is okay. If you want to be safer: Make another backup on an extra storage device before resizing part5. I am not sure how stable btrfs is.
