I mentioned last week I was having problems doing index restores after
renaming a server.  This was after migrating from Solaris to Linux via a
DR restore, which worked just fine.

I contacted Legato support, and they pointed me to technical bulletin
396: How to Rename a Networker Release 7.1 Server (UNIX)  This had a
different procedure than the previous tech bulletin I was using (365.)
Following the 396 procedures allowed me to do index restores after the
server was renamed.

FYI,
Dave
