What do you mean by "Primary"? Do you only have one AFS DB server for
your cell? Most cells run at least 3 AFS DB servers (just look through
the CellServDB file.)
When you say "second," what do you mean?
I have two DB/PTS/file servers; the "primary" has IP xx.12, the second
server xx.16.
You probably want at least three VLDB, PTS, (and possibly BackupDB, if
you use that) servers total. (So that two are up at any given time.)
Ubik (syncronization protocol that AFS uses) grants an extra vote to the
server with the lowest IP address, and if the server you take down has
the lowest, you might not reach quorum and bad things can happen.
Okay - I will set up a third VLDB/PTS server.
5. Copy /usr/afs/db, /usr/afs/etc/, and /usr/afs/local from the old
system partition to the new one. Mount /vicepa same as on the old
system.
You should NOT copy /usr/afs/db. These DBs will auto replicate from the
other server and there is no need to pre-populate that directory. In
fact, doing so may cause problems. And you can have all kinds of issues
if you copy the sysid file from another server (this might be better
now, but in general copying unique identifiers is NOT a good idea.)
Also be aware that different servers may have different NetRestrict or
NetAllow files and you don't want to copy them.
In this case, tho, I am not copying from another server but from the old
installation of the *same* server. Under those circumstances, don't I
want the sysid file to be the same?

Don't forget that upserver and upclient re-populate the /usr/afs/etc
directories automatically.
This machine is the update server, however - will it get repopulated or
will it depopulate the others?
