Can't seem to find my previous reference to upgrading clustered ASAs in master/slave config. Can someone please verify if the following looks correct? Also... does the nomenclature change from Master/Slave to something else when going from 9.2 to 9.12?
This is a pair of ASAs running 9.2 ... I want to bump them to 9.12 (as I recall, I tried 9.14 previously and ran into an incompatibility with the current cluster config and a feature that was introduced in 9.13).
Assume that I am doing this directly connected to console with the 9.12 and ASDM images on a USB drive. ASA1 is master, ASA2 is slave in a cluster group called "BC".
1. Copy the 9.12 image to disk0: on each ASA
2. Make the new image the default boot image on each ASA
3. Do the same with ASDM image
4. From ASA1, issue: "cluster exec unit ASA2 reload" command and then check with "show cluster info" to verify it comes back on as Slave and is running 9.12
5. Issue "cluster group BC" and then "no enable" to disable clustering on ASA1 (master).
6. Reload ASA1
When ASA1 comes back up, I should be able to see that ASA2 is now master and ASA1 is now slave. I can change this back with "cluster master unit ASA1"
Thoughts?
