Changing controller numbers in /dev manually

Hello Gurus!

I've been looking for an answer to this, but I can't seem to phrase the
question properly. I need to change a controller instance in the /dev device
tree to another number manually:

e.g. /dev/dsk/c2tXd0sX to /dev/dsk/c4tXd0sX

I know about devfsadm -C to clean up entries, I can disconnect the arrays
and start fresh, but I need an absolute assurance. Without doing it
manually, I can't get that. I've tried looking around a bit in devlinks.taband
devices.tab, tried manually changing files and links in /dev to no avail.

SunFire 280R, Solaris 8 02/04, with fully populated StorEdge D2.

Any help anyone can give would be greatly appreciated and I'll post a
summary after answered. Thanks!
