Hello Team,

Hello,

I have good experience on Commvault environment upgrade 

but I want some advices about HSX environment where I a not very familiar

CommCell version is 11.34.47 End of life target version is latest 11.36

Current HSX Clusters info :

whichCommit.sh
Branch: QBDQv-5.0.8.2]

rpm
hedvig-common-5.0.8.2_3820_f13a4ee0db-1.el8.x86_64
hedvig-cluster-5.0.8.2_3820_f13a4ee0db-1.el8.x86_64

In a standard environment, I update :

1 - Commserve Linux PROD
2 - Commserve Linux DR
3 - Media agents one by one, and I connect to each media agent to perform the update locally not push
4 - Access nodes
5 - Index cache Servers
4 - update clients 

I thing for HSX environment it is the same order :

1 - Commserve Linux  PROD
2 - Commserve Linux  DR
3 - HSX Cluster 1 
3 - HSX Cluster 2
4 - Access nodes
5 - Index cache Servers
4 - update clients 

My question is about HSX Clusters update. I am confused about OS upgrade, CVFS update, which order, service disruption during update, anyone can clarify please ?

Thanks for the help !
