In the "For What it's worth" category, if I were building a new
NetWorker server, I'd use a new name. We migrated our old NetWorker
server to a new one, with a new name. There is a tech note on how to do
it, it is easy if you follow all the steps. Of course, we went from AIX
5.1 to AIX 5.3.

One advantage of chaning names, is you can test the new server before
you completely make the switch.

In other words, you build the new server, when you are ready to test the
migration, you shut down the current server, bring up the new one. If
everything works fine, great, but by keeping the current one in place,
you have something to fall back to, and you do not have to stop your
production backups.

I am not sure how many clients you have, or how you have them
configured. We only had about 80, and it did not take all that long to
change everything.

As for licensing, assuming you have a support contract, it is real easy
to re-license your new server and all the associated clients.

The folks at EMC/NetWorker are real helpful.

I would drop those PIG SLOW LTO-2 drives. (Yeah kinda spoiled like
that)... But outside of that your config looks ok.

Keywords... "Redundant bandWIDTH".

Quite honestly, I am very intested in your project. Could you please
document your steps & trials and share them with me...errr, I meant to
say US, yes US. <Grin> that being said...

I would not want to do what you are doing (rebuild using same name,
etc.) my gut is telling me safety is in a new hostname.

Licensing Oy-Vey... Nightmare on EMC drive... EMC FOLKS, can you post a
reply to the list and tell us this answer? E-GOLD, if EMC doesn't pipe
up, please share the answer they give you?

Hi All,
I have a legato 7.3.2 jumbo 1 server running on win2003.

I want to migrate over to redhat 4 linux as painlessly as possible and
keep all my configs , etc.

What is the best way to do this? Do I need to get new licenses?

I want to named the linux server with the same hostname as the windows
server so the clients dont need to be touched.

Do you think I would get better performance on linux vs windows for the
same hardware?

My server will be a new  HP with 2 fast quad core cpus (total of 8
cores), 8GB RAM, 6 fiber channel LTO2 tape drives, and a quad NIC card
teamed up.

Thanks.
