Hi,

I have recently migrated a networker server with Data Domain devices from an old host with Windows 2008 R2 to a new host with Windows 2012 i followed the document generated by Solve Desktop and after the migration when you check the Networker instance name from the properties of the Networker server in NMC i still see the old server hostname although the backup and everything is running on the new hostname without any problems.

But when i try to reinstall the Networker software or upgrade the software the instance name is changed to the new hostname and all the the configuration disappear from NMC (Like clients - Groups - Devices)

and i have to run the command "mmrecov" to recover the bootstrap and all the configuration back.

Below is the output in NSRLA record:

nsradmin> print type: NSRLA

I replaced the original hostnames with old_hostname and new_hostname

I will upload a screenshot of the NMC to explain what i see.

how to fix that?

Thanks,
