[Networker] solaris to linux migration

Hi George,

It works, you have to use mmrecov to move the res and mm over, but itisn't officially supported, as you noted. Indexes can actually bersync'ed over, so you don't have to do them all at once, rather thanhaving to restore them from tape.

After you migrate, you'll have to manually edit the res (via nsradminin offline mode--nsradmin -d /nsr/res/nsrdb, when networker is shutdown) to fix the difference in notifications between Solaris and Linux.

Licensing will go into grace mode for 15 days, so just make sure theoriginal box is shut down, or at least networker is first.

Other than that (and a few other details--stinit.def and similarstuff), just follow the normal steps on "how to replace a networkerserver with a new box, using the same hostname as the original one".

Subject: 7.4 from Solaris to Linux?

Kind of a dumb question here, but would there be any reason to believe
that NW 7.4 on a Solaris primary backup server could not be transferred
to a RH Linux primary server any less so than NW 7.2.2 could?

We are anticipating moving our NW server from Solaris to Linux - yes,
that's a whole other discussion that has been hashed out many times on
this forum - but we will not have this Linux machine available for some
time. In the meantime, we would like to upgrade our current Solaris NW
7.2.2 server to 7.4. I would think that later down the road, we could
simply install the same release (whatever that might be at that point)
on the Linux box and recover our indexes, resource and media databases
from tape (basically a disaster recovery) to allow the proper conversion
and *best* avoid any possible byte ordering problems between the two OS,
even though not officially supported by EMC-Legato (ahem). That sound right?

Thanks for any comments.

We're running 7.2.2 on Solaris 9 with two RH Linux snodes. Not sure what
RH version we would be transferring the primary server to, though.
