I use the create controlfile command regularly to move databases between
UNIX systems with differing numbers/names of disks.
Basically: use the alter system backup controlfile to trace on the existing
system. Shut it down cleanly. Copy it to the new locations. Edit the trace
file that you generated with the create controlfile command in it to reflect
the new disk locations and run it. Simple and reliable.
