Upgrade procedures have been discussed thoroughly in CSC, your first step is to review the install and upgrade guides for CUCM 9.1, along with the Release Notes, all available upon search on cisco.com. Or, under cisco.com -> support -> Product Support -> all products, and then browse to CUCM.

You can also do some further reading from the D29 material
