I am attempting to upgrade my Master and Local controllers from 6.4.2.6 to 6.4.4.9. My Master Controller is currently running 6.4.2.6 and before I upgrade it, I wanted to set up the Configuration Files option and have it point to my FTP server where I have ONLY the latest images that will be used to upgrade. But when I click verify, the Master Controller shows me images that it is currently running and not the images that are on my FTP server. Why is that? Will it only show the images for the current AOS that it is running? Will it actually go and grab the latest images once I upgrade the Master to the latest firmware?
And a second question...when I upgrade the Local Controllers, will it install the latest firmware on the INACTIVE Partition and then boot from it (reserving the boot partition with the older firmware in case of rollback), or does it simply install it onto the current Boot partition and overwrite the older firmware? On some of my Local Controllers, the Inactive Boot partition has even an older version (like 6.3.1.X), so I really want to make sure that if I needed to roll back, I could still boot back into the 6.4.2.6 that we are currently running.
Thanks.
