We have a site with maybe 1-200 cisco network appliances. These are a mix, old and new including SG350, ESW520, Nexus9000, C2960's, just a mess of various models.
I've checked each switch for current firmware version. My task is to determine the latest firmware version for each, and an upgrade plan (major versions required to be installed between current version and latest).
Is there somewhere I can go, or a resource I can contact or access for this information?
Is my only bet to google each model, check the latest version, then dig through old documentation to try to determine if the device can be upgraded directly to latest?
Any helpful info is appreciated.
Thank you
