+upgrade utility which can show db info and help transfer data between databases, for example when a new version of copyparty is incompatible with the old DB and automatically rebuilds the DB from scratch, but you have some really expensive `-mtp` parsers and want to copy over the tags from the old db
 
-for that example (upgrading to v0.11.0), first move the old db aside, launch copyparty, let it rebuild the db until the point where it starts running mtp (colored messages as it adds the mtp tags), then CTRL-C and patch in the old mtp tags from the old db instead
+for that example (upgrading to v0.11.20), first launch the new version of copyparty like usual, let it make a backup of the old db and rebuild the new db until the point where it starts running mtp (colored messages as it adds the mtp tags), that's when you hit CTRL-C and patch in the old mtp tags from the old db instead
 
 so assuming you have `-mtp` parsers to provide the tags `key` and `.bpm`:
