We are starting the process of upgrading our enviroment to UCS and are going to start with Connection. We need to upgrade it 7.1(3) inorder to do the jump upgrade. The write cache battery has failed on the server. The server is EOS and we have purchased a replacement battery pack and it was good for a few weeks but it now shows to be failed again. Is it possible to proceed with the upgrade even though the battery is failed? Wewill be moving off this platform as soon as we can perform the upgrade steps.
The jump upgrade procedure is ONLY for CUCM, anything else. For CUC your options are to either upgrade to (at least) a CUC version which supports virtualization to DRS backup/restore, or to use COBRAS.
From I am reading this states that you can upgrade the connection server to 7.1(3) and then install that same version on the UCS and restore the DRS. This can then be upgraded to 9.X, perform a DRS backup. I assume you would then do a clean install of 9.X and do a DRS restore. I might not be reading it correctly. If the Cobras method is used is anything lost in the migration of the data?
Before starting an upgrade, verify the status of the write-cache on the MCS-7828-H4 and MCS-7835/45 disk controllers. You do not need to verify the write-cache status on the MCS-7816, MCS-7825, or other MCS-7828 servers. To verify write-cache status, access the Cisco Unified Operating System Administration, and choose Show > Hardware.
If you determine that your write-cache is disabled because of a dead battery, you need to replace the hard disk controller cache battery. Follow your local support procedures to get this battery replaced.
The following example shows write-cache enabled. The example indicates that 50 percent of the cache is reserved for write and 50 percent of the cache is reserved for read. If the write-cache was disabled, 100 percent of the cache would be reserved for read or the Cache Status would not equal "OK". Also, the battery count equals "1". If the controller battery was dead or missing, it would indicate "0".
So the next step here is to have a look at the show>hardware

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
