Upgrade VSLS R80.10 to R80.20

[Michael_Rolbin]

Is it supported to upgrade R80.10 VSX VSLS cluster to R80.20 VSX VSLS cluster, including MDS or Smart Center, upgrade?

I checked "Installation and Upgrade R80.20 Guide" page 334 and it looks supported for "VSX Cluster". 

Could you please confirm that for VSLS?

VSLS and ClusterXL HA are the 2 clustering methods of a VSX cluster, so by using the terms VSX cluster you include VSLS.

Thank you, I just needed a confirmation that there are no different processes to apply for VSLS specifically.

Referring to documentation:

https://sc1.checkpoint.com/documents/Best_Practices/Cluster_Connectivity_Upgrade/html_frameset.htm

As far as I know, no transparent upgrade can be done on a VSLS VSX cluster. The requirement here is running HA. Correct me if I'm wrong.

@Vincent_Croes You are wrong. Look into Connectivity Upgrade of a VSX Cluster in the document above. It is relevant for all cases, VSLS or HA

There are prerequisites in doing a CU. See screenshot above. Explains why the procedure mentions members M2 and M3 being in standby seeing that my production members have more then 1 state running on a single member.

What am I missing?
