Relocation from one networker server to another in unix

[unixdaemon]

Has anyone performed a successful relocation of Networker's /nsr directory to another UNIX server without the licenses? If so can you provide the steps in which to do this process?

My problem is that I have to upgrade the hardware on a Legato server (from a Sparc 5 to a Netra) and I want to know what files in the /nsr directory I need to move over to the new server without manually typing in the configuration for storage nodes and such. I understand that I am going to have to manually type in the new license information. I am running Networker 6.1.1. I already have the new licenses. I don't want to manually type in all the information that is needed to configure the Legato server and it's storage nodes. Does anyone have suggestions or has anyone had success in this area?

I've never done it myself, but Legato's TB on the subject would seem a good thing to follow. Seems it covers a lot more possible gothcha's then just your license worry.

Hi unixdaemon
tar cBvf /dev/rmt/0cbn /nsr

New server :

tar xvf /dev/rmt/0cbn

tech bulletin 121 has good information, but keep in mind that it is not updated for NetWorker 6 or 7.

Essentially the task would be to:

- On the old server, perform a bootstrap and index backup
This can be donw by creating a special group, putting all your clients in that group, then backing up the bootstrap and indexes by running: savegrp -O -l f (group name)

- stutdown NetWorker on the old server

- install the software on the new server

- recovering the bootstrap on the new server with mmrecov command, and indexes with nsrck -L7

- stutdown NetWorker on the new server

- rename /nsr/res.R to /nsr/res

- restart NetWorker

That's the essential steps. You also will need to ensure that the tape drive on the new server can read the tape from the old server (st.conf settings, st driver patches),
and get a host transfer license from legato.

If you start NetWorker on both new and old servers at the same time, they will detect each other and then disable both servers.

Shortcut: instead of recovering the indexes with nsrck -L&, you can just copy/tar them over. This only applies to the index; you cannot do this with the media database. It may seem to work, but there is no guareentee that the data in the resulting media database would not have corruption.
And you may not see the corruption till later when you need to recover data.
