[cisco-voip] CCM upgrade 3.2(2)c to 4.1(2) - Steps and Experience

[Hering, Marc]

The 3.2.2(c) to 3.3.4 wasn't bad at all.  You DO have to reimage the
entire MCS however.  When you use the PUT to order your upgrade disks it
will come with an upgrade guide of step by step instructions....Follow
these EXACTLY and the upgrade will be smooth as silk!  (took me about 4
hours to do both CM's and that was only because of the OS install and
patching)

If you check the compatibility mattrix, 4.1(2) has some minimum
requirements, one is a 4.0.x and one is a 3.3.x 
 
We have chosen to go to 3.3.4 first, then to 4.1.2.
 
You will need to order the disks and perform an upgrade from the disks.
I did it all in under one hour I think. The 4.1(2) upgrade, not the
3.3.4 upgrade.

	What steps do I need to do to upgrade from CallManager 3.2(2)c
to 4.1(2)?
	 
	Can I upgrade to 3.3, run a BARS backup (latest version), then
do a clean install of 4.1(2) and restore from BARS?  I also have a
Subscriber to upgrade.
