UCS Central Upgrade: 1.2(1a)

After downloading the appropriate .iso file for your UCS Central upgrade (the most current version is 1.2(1a)), map it to your server, and reboot.

Some details you need to consider from the Upgrade Guide:
-You can only upgrade to 1.2(1a) from either 1.1(1b) or 1.1(2a)
--Clear the browser cache after logging into the UCS Central web interface
-You must upgrade from 1.1 to 1.2 versions in standalone mode (cluster mode can be enabled from the loca-mgmt CLI level)
-You can only use the ISO image upgrade (Provider Bundle is not longer in use)
-UCS Central 1.2 supports UCSM 2.1(x), 2.2(x) and 3.0.  Upgrade UCSM BEFORE UCS Central, or deal with mismatched version faults and missed updates on UCSM side
-Be aware that once you upgrade, you cannot downgrade :]

Again we are presented with the option to install or upgrade, as was seen in the Installation post.  This time we are going to elect to "Upgrade existing Cisco UCS Central".

Let's move on to configuring this bad boy...
