Has anyone performed a rolling upgrade from Solaris 11.3 and OSC 4.3 to Solaris 11.4 and OSC 4.4 ?
We plan on upgrading to Solaris 11.4 and OSC 4.4 on a HA-ldom cluster , and would like to eliminate any ldom downtime. We have read through the upgrade documentation etc. and think we are aware of most of the possible problems/recommendations. In our case we need to update to Solaris 11.3.35 first, we are already on OSC 4.3.12. One of our question is, do we get both nodes on 11.3 SRU 35 first, or can we upgrade one of the nodes to 11.4/4.4 first, then live migrate the ldom's and then upgrade node 2 ?
