	I did a fresh download of all of the directory tree, deleted the update
and update.last targets in coda, and tried doing the mv command above
(the third command) by hand.  After the move there weren't any
conflicts, but the mv command returned some funny error messages.  The
bulk of the messages were reporting problems with changing the
permissions, which I know I can ignore:

/bin/mv: preserving ownership for `/coda/.../update': Permission denied

But towards the end of the mv operation I saw a few errors like this:

/bin/mv: cannot create regular file
`/coda/.../update/remupd/@7f000001.00000c94.00009927_at_director': Invalid
argument

	I have tried checking to see if these mystery files exist, but it
doesn't seem they do:
# cfs getpath 7f000001.00000c94.00009927_at_director
VIOC_GETPATH: No such file or directory

	During the move command, these console messages appeared:

	I'm giving these details because I want to know if these log messages
are ignorable.  And also because I have a suspicion that things will
break at the next step (renaming the target directory and then copying a
new tree over to the old name).  So here are some excerpts from
venus.log:

	Lots of messages like this:

[ I(51) : 0041 : 17:29:25 ] k_Replace: VenusFid
(5086c448.7f000001.fffffffe.82f5f) with VenusFid
(5086c448.7f000001.9ec.d63d) in mini-cache

	Several exchanges like this:

[ I(51) : 0041 : 17:29:26 ] ClientModifyLog::COP1: (replica 1) 0 stale
dirs
[ I(51) : 0041 : 17:29:26 ] ClientModifyLog::COP1: (/httpd), 8712 bytes,
returns 0, index = 100

	And here's the excerpt from around the time that console reported
"volume /httpd CML is busy, skip checkpoint!":

[ I(51) : 0041 : 17:29:37 ] k_Replace: VenusFid
(5086c448.7f000001.fffffffe.82fa0) with VenusFid

[ T(01) : 50435 : 17:29:38 ] BeginRvmTruncate (1344, 372884, S)
[ T(01) : 50435 : 17:29:39 ] EndRvmTruncate

[ I(51) : 0041 : 17:29:39 ] *** Long Running (Multi)Reintegrate: code =
-2001, elapsed = 2207.4 ***
[ I(51) : 0041 : 17:29:39 ] ClientModifyLog::COP1: (replica 0) 0 stale
dirs

	I'm going to continue the process and see if any conflicts appear. I'm
controlling the environment by preventing other reads/writes to coda
while doing this.
