We are planning to upgrade our ESM from 12.4.xx to 12.5.3.
As it's at big installation we need to know if it's possible to upgrade in steps (is the agent backwards compatible ?)
Which combinations will work, of the below configuration :
Agent AM . CAS
12.4.5 . 12.4.5 . 12.4.15 . Current Setup !!
12.5.3 . 12.4.5 12.4.15 ??
12.4.5 . 12.5.3 . 12.4.15 ??
12.5.3 . 12.5.3 . 12.4.15 ??
Hope for a quick reply :-)

ESM 12.5 requires RUM Console and CAS of the 2017 release. You should upgrade your ESM installation to the 12.5 release after your DC RUM 2017 is up and running. See the Upgrade checklist here: ESM upgrade checklist
