We just purchased a 5508 HA to pair with an existing 5508 for HA SSO. Without thinking about the backup images I upgraded the new 5508-HA to 8.5.161.0. It has been a while since I did this. Then noticed that the backup images are different; 8.3.140 on the new 5508-HA controller, and 8,5,140.0 on what will be the primary 5508.
So on the 5508-HA the default active is 8.5.161.0 and the backup is 8.3.140.0. I want both to have 8.5.140.0 as the backup image and 8.5.161.0 as the primary. Can I just boot back to 8.3.140.0 then upgrade to 8.5.140.0 then configure the config boot so that the default active will be 8.5.161.0 with a backup image of 8.5.140.0? If not what is the best plan of action here.
Thanks in advance
