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.

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.
