hello brent,

though i don't know anyone who has gone this route, i imagine it is
possible.  the reason most people don't cvsup from 4.x to 5.x is because
there is a fundamental change in the filesystem (details of which escape me
now - check the release notes at freebsd.org).  by simply cvsupping, you
will _not_ be able to take advantage of the new filesystem.

if your customer insists upon 5.x, it would probably be best to prepare a
full back-up then:

a) take the machine down, make a fresh install of 5.x, then load back data.

b) build and configure a parallel 5.x machine, load it with the backed-up
data, then find a new use for the 4.x series machine.

hth.


cheers,
epi
