Re: [Networker] Migrating from Win2003 32bit to Win2008 64bit

I did migration such an OS+Networker migration on the fly,
from a Win2000+NSR742 to Win2008R2/64bits+NSR7531 but not
with disaster recovery /mmrecov procedure: 

My legato bin, data and index being under D:\Legato drive,
I prepared new Win2008R2 Server and installed NSR7531 kit+
savegrp hotfix (or now 7532) into temp D:\Legato.
Stopped Networker services and saved D:\Legato dir from which 
I removed res, mm, index and logs sub-dirs and set networker
services as manual startable.

I did stop win2000 server properly, unmapped the Networker San 
disk from old server and mapped it to the new one.

I renamed new Win2008R2 Server with same hostname that
Win2000 old one and booted like a charm. I replaced from
the disk the old D:\Legato with the new one, keeping 
RES, INDEX, MM directories.

About drives, I created Persistence reg key to
keep tape device name permanent and had to reconfigure 
library (lib scsidev path and drive name).

Finally started Networker like a charm.
(You can also create a Windows Snapshot of the HDD in case of
for easier rollback in case of)

Just then had to reauthorize lics from EMC Licencing dept.

All is ok since such migratopn.

Good luck,

About the Persistence registry key
1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. Locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Tape
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type Persistence, and then press ENTER.
5. Right-click the Persistence registry entry, and then click Modify.
6. Type 1 in the Value data box, and then click OK.
7. Quit Registry Editor.
8. Restart the computer.

After the reboot, the tape devices won't be called \\.\Tape0 anymore. They
will be like \\.\Tape64364 and they will persist across reboots and topology
changes.

Hi Paul,

The mmrecov will bring back all of the NetWorker Configuration minus the
client file indexes. Also the path to the current installation will need to
be the same on the new server for the mmrecov to work correctly.

Thanks,
Mark
