Actually, you're still exposed there.
The procedure goes:
DEF DBVOL new
DEF DBCOPY new new-copy
DEL DBVOL old-copy
[D'oh! old is now unmirrored]
DEL DBVOL old
and for however long it takes you to copy, you stay unmirrored.
Now, this is not a huge exposure, in the scheme of things. But it
-is- an exposure, and I don't see a reason for it. I've wished aloud
here in the past for something like 'EMPTY DBVOL' so you can move data
off a mirrored volume onto other mirrored vols.
