I would highly recommend purchasing a lab license in order to test/practice/validate your documented upgrade process.
Personally, I export an SCF file from all my devices and import them into an isolated lab VM instance. I have to massage a few properties, of course, like commenting out interface configs and what-not in the conf files in order to get them to load. And although I can't run actual traffic through it, I can at least determine what, if anything, will break the upgrade process and document/remediate those things before the real upgrade is performed. This scheme has proved invaluable and saved me a lot of headaches and sleepless nights.

Hi Experts
Will UCS archive work from 10.2 to 11.6? If we take backup in older version 10.2 and then restore after upgrading to 11.6?
This is just in case the documented process of upgrade fails at some point.

Hi Experts
I recently did an upgrade from 10.2.2 to 11.6.0 HF5. The devices were in active/standby HA. After rebooting to new volume, the configuration got wiped out. Only Self IPs, VLANs and interfaces stayed, along with host name and system details.
HA went down as well. I manually configured the F5, referring to the old snapshots, tried to re-sync, but HA never came up at all. Had to revert back due to outage window being limited to 3 hrs only.
Syslog was filled with the below messages:-
01071432:5: CMI peer connection established to 192.168.11.1 port 6699 0107143c:5: Connection to CMI peer 192.168.11.1 has been removed
01071431:5: Attempting to connect to CMI peer 192.168.11.2 port 6699 0107142f:3: Can't connect to CMI peer 192.168.11.2, TMM outbound listener not yet created
All config-sync and peer IPs were working fine, reachable within same network.
Any advice please, maybe it is time for TAC support?

Sumanta,
Off the top of my head, the MGMT IP address cannot be used for Config Sync/CMI Peer in version 11, so can cause issues.
I would take the opportunity to configure an additional VLAN on neighbouring switches for HA + Config Sync.

Hi Iain
Thanks, but I have both mgmt and internal HA VLAN. Even then, it doesn't work.
