Backup Central

We've migrated the vast majority of our backup environment off Networker
but I've been informed that we won't be allowed, as we previously thought,
to migrate one server and its five clients. That one is still running 7.2
on Solaris 10. Very much unsupported, we know, and it's indeed slated for
upgrade when we get time (yeah, right... take a number , but for now
it's out of sight, out of mind on 7.2 and running without complaint. This
will also be new server hardware, so at least that makes it a bit easier -
We can tar up /nsr to tape and lay it back down on the new server, saving
a lot of reconfig work while still keeping the old server in production.

Q: Can we go from 7.2 to 7.6.1 in one fell swoop, or will we have to stop
at (say?) 7.4.x along the way? Any gotchas?

Thanks.

I doubt that anybody ever did that. However, except for the update enablers, i do not remember a general technical problem.

In general, you have the choice:
- either you upgrade in multiple steps or
- you update directly risking that you might need to go back (by recovering a bootstrap) and then do it step by step.

Actually, we should be able to avoid the whole mmrecov / etc. mess since
we'll have the tape of all our indexes and such under /nsr. We've done
this many times in the past (install packages and replace /nsr from our
tape).

Not that we have any time RSN to do this, but I'm just trying to avoid
issues. Sounds like I might want to call 1-800-PowerLink when we're ready.


Thanks for the feedback.

Hi Len,

There are release notes along the way that mention a drastic database change that requires an interim step.

We moved our /nsr from rhel3 7.2 to rhel 5 via tar and installed 7.4 straight away on the new OS. This tested after we reconfigured devices so we upgraded to 7.6 from 7.4 in place on this new machine. Our goal was to avoid installing 7.2 packages on rhel5 which seemed muck things up.

Seems to be working fine maybe this workflow would work for solaris.

Well fortunately, this will be all on Solaris 10/SPARC so there's no
change of platform nor OS version. But I'll need to verify we're all OK in
terms of upgrade enablers, exact sequence and such along the way, so I'll
open a case on PowerLink when we're ready to go.

Thanks for the info.
