In fabric environment can we apply different versions with different patches ?

Issue

• Currently we running fabric setup with 3 ensemble nodes with version 6.3-R4. We are managing 3-4 env using same fabric setup. Now since we got new Rollup Patch-R6, so we would like to upgrade only one of the env to 6.3-R6 and leave rest on 6.3-R4.

• I know that we can create new version and then apply new R6 patch on newer version, but I am bit confused that on my ensemble nodes if we upgrade to R6, then how this will affect env which are running on R4.

• Lets suppose currently 3 ensembler nodes using version 1.0 with base installation as 6.3-R4 and we created new version 1.0.1 which have patch 6.3-R6. So, when I'll upgrade all ensemlble nodes to 1.0.1, how this will affect the remote container which will be running on older version i.e. 6.3-R4.
