[cisco-voip] Upgrade from CM 3.2 > 3.3 > 4.1

[Glen]

Digger,

You will need to be aware that during the upgrade process from 3.2 - 3.3 a
rebuild of the server will be required, as 3.2 uses SQL 7 and 3.3 uses SQL
2000. Therefore I would not be too worried about installing 3.2 on 2000.2.7.

Is the production cluster at the latest SR release for 3.2? e.g. 3.2.3 SR 2?

If so I would install the upgrade assistant on the existing servers and
confirm that there are no issues with upgrading the server, perform a backup
using the latest MCS backup.
Then build your new cluster using the 3.3 CDs and then restore the backup
from the old cluster, before upgrading to 4.1.

Hope this helps.

Glen

Yeah.  Thats the plan, to run the new environment and complete a very
detailed test plan on it.  I was just concerned about getting CM 3.2 to
the new MCS hardware.  It looks like I can do a new install of 3.2 on OS
2.7.  I could swear there was an issue with installing 3.2 on an OS that
had Windows SP4 way back when.
