Best Practices to upgrade cluster and sandblast TE

Hi All,


Have a good day.


I have a question about the best practices to upgrade a cluster xl and a sandblast TE appliance.

Currently we already done for upgrading management server from R80.20 to R81.10 and the rest left 2 cluster and 1 sanblast TE.

I already read installation and upgrade guide R81.10, but i still confuse what is the best method for this upgrade.

because my customer have a internet banking on the cluster inet fw, so i think this upgrade will be critical since on that cluster have a mobile access for IB, i need the best practices for use either CDT or i just upgrade each member as a independent security gateway.

Can anyone give me advice the best practice for upgrading cluster? which have a mobile access ( portal ) like internet banking.

and another thing is about the portal of mobile access is also change from R80.20 to R81.10, can i revert to the version of R80.20.

for sandblast TE, can i upgrade this via CDT? or i must upgrade via CPUSE.


If you still confuse about my question, please let me know.


Thanks Regards

The best and reliable method is always CPUSE. Upgrade the device one by one and you should be fine.

See Installation and Upgrade Guide R81.10 p.401ff for Zero Downtime Upgrade of a Security Gateway Cluster: Best Practice - Use the Central Deployment in SmartConsole. CDT does use CPUSE but works from Dashboard.
