Hi everyone,

We have three AFS Cell servers, and we need to change the IP address for on=
e of the cell servers and a few (one-third) of the file servers.  This is c=
aused by an upgrade and reconfiguration of our network. The machines will n=
ot physically move or lose power. We used static CellServDB files and don't=
 use afsdb or DNSSRV records for our cell.

I know that I need to push out a new CellServDB to the servers and clients,=
 but what is the best procedure? Do I need to restart all of my AFS servers=
? What will be the impact if I  don't touch  the non-rehosted file servers =
and let them perform a service restart as part of the weekly restart?

I know the new IP address of the cell server, so I could push out the CellS=
ervDB file ahead of time, if that will make things easier.

I know that I can use "fs newcell" on the clients to avoid restarting.

Thanks,
Jason
