[OpenAFS] Server down, other server ready to serve its data: vos delentry question

Hypothetical Scenario:

     AFS fileserver 'downserver' is down and unbootable.
     It served both RW and RO volumes.  A list of these
     volumes is attainable via vos listvldb.  Let's assume
     'downserver' is going to have to be down for a week.

     AFS fileserver 'up' is up.

     AFS fileserver 'up' has 'downserver's old /vice
     partitions mounted (they are no longer physically
     connected to 'downserver').

     fs has been restarted on 'up'.

Questions:

I can't easily test these.

Obviously a 'vos syncvldb up' needs to happen at some point.

1.  Is it necessary (and wise) to use 'vos delentry -server
     downserver' beforehand to avoid VLDB issues?

2.  OR... will 'vos syncvldb downserver' then 'vos syncvldb
     up' cause the dead VLDB entries to clear out due to the
     server being inaccessible?
