You should upgrade to 8.6 on MCS, take a backup, build 8.6 on UCS, restore backup and then upgrade to version 10.0. 7.x version is not supported on UCS except jump upgrade scenarios as a part of Drive to 9 initiative.
My client has standalone 7.1.3 on a MCS 7845-H2 (Version 1). My plan is to upgrade 7.1.3 to 8.6.2 and restore it on VM and upgrade it to 10.0.
Cisco told me that with one CUC in production I just need to remove last four HD from the MCS 7845-H2 and CUC will be capable to be upgraded to 8.6.2 on the MCS. He said I do not even need to upgrade RAM from 4 to 6 G, I am not how safe is this approach.
I am thinking to use COBRAS for the upgrade from 7.1.3 on MCS to 8.6.2 on VM.
Please let me know your recommendation about options of removing the HD and COBRAS.
Cisco just got back to me and is said "According to the version we have, you are correct; the documentation mentions we may need to replace it to 146 GB (even if it isn’t a cluster) and Having 6 GB of RAM"
