CUCM Maint Release Upgrade

Question

Hello,
Can anybody advice how my customer can upgrade its CUCM's maintenance release from 6.0(x) to 6.1(x) ?
It is an existing implementation and the customer has not ordered CON-ESW-* SKUs previously ?

Hi Tobivan,
No worries my friend, this is my fault for not reading carefully :) In your first post you mentioned upgrading to 6.1(x) and I assumed (I know!) you meant 6.1(2). You **can do the upgrade you were actually talking about with the method you referred to as well. This was CCM 6.0(1a) to 6.1(1). This is shown below.
Use the iso files mentioned in the "Upgrading from Cisco Unified Communications Manager Release 6.0(1a) or 6.1(1a) to Release 6.1(1b) Using the UCSInstall File" section for upgrades from 6.0(1a) or 6.1(1a) to 6.1(1b) only.

I wrongly was still talking about the upgrade path from 6.0(1a) to 6.1(2) which is not supported using the ISO Files.
***Caution: Use the ISO files that are mentioned in the "Upgrading from Cisco Unified Communications Manager Release 6.0.(1a) or higher to Release 6.1(2) by Using the UCSInstall File" section for upgrades from ***6.1(1x)only.

Hope this helps! Sorry about that.

PS: I would still think about going to 6.1(2) as this is a very good, stable build.
