Hi All,
I need to replace 3220 in HA to 1420 in HA.
- The 3220 running 11.1.3-h3
- I installed 11.1.3-h3 on the new 1420s.
- Installed the same version of the apps and threats.
- exported the running config from the 3220
- imported the config to the 1420 and ran a commit.
I read that i cannot run the HA with different platforms. Is there a way to do a 0 downtime or only hard cutover to the new HA?
