I have been through a number of documents about the Upgrade of 4.1.3 to 7.1, however most seem to indicate a "in-place" sort of upgrade.
I need some advice/documentation which details the step process of doing a parallel 7.1 build of CCM on another set of hardware and then migrating the users base from the 4.1.3 setup. My hardware is a bit suspect and could do with a spec upgrade to for this purpose.
1) Can it be done like this?
2) Where can I find some documentation for this sort of "migration".
3) Anyone done something similar ? And would like to share the experience?
Thanks for you help in advance.
This is a supported and highly desireable method of Upgrading from the
older windows versions
Even with the new build of CUCM 7.x on a new box you can choose the Windows Migration option using the Data Migration Assistant (DMA). Just run the DMA on the old CCM 4.1(3) before you start and it will produce a .tar file that can be used to move the data across to the new version;
Import Windows Data
This option allows you to import database information from a Cisco Unified Communications Manager 4.x system by using a file that the Data Migration Assistant (DMA) tool produces.
Upgrading the First Cisco Unified Communications Manager Node
When you choose Windows Upgrade, the installation wizard prompts you for the location of the preexisting Windows configuration information that the Data Migration Assistant (DMA) tool created. See the Data Migration Assistant User Guide for more information on the DMA tool.
Step 1 - In the Windows Upgrade window, import data from a Windows version of Cisco Unified Communications Manager by choosing Yes

Hope this helps!
