These instructions might help.
You don't need to set up a KDC, but you must make sure that the
Linux server can kinit against the AD servers.
Is there any reference to the old DB servers in /usr/vice/etc/CellServDB
or /usr/afs/etc/CellServDB or /etc/openafs/CellServDB? If so remove the
references to the old servers. Are you using AFSDB entries in DNS?
