My experience upgrading is that Devuan doesn't require /usr merge on
upgrade from Chimaera to Daedalus and simply keeps your existing file
structure and doesn't move files in /bin, /sbin etc.and replace them
with symbolic links to /usr/bin, etc.
So everything is still as before.

However I don't have a separate partition for /usr, just for /home so
can't speak directly to that situation.
