Yes, it will.
from "vos help | grep delentry " :
delentry        delete VLDB entry for a volume

The actual volumes on the fileserver are not touched by this.
Only the database saying  which volumes is where (the VLDB) is affected.
Also, syncing the VLDB does not delete any data on the fs.

The pts is only involved when you have ACLs including the old IP.
