We have pair of 5800's in HA ClusterXL setup in our datacenter. We have a pair of 9200's on the way. All our CP GWs and Mgt are currently R82 JHF 39.
I have read a little about ElasticXL but not sure how to get there from our ClusterXL setup -- or if it really will see any benefit. We are Healthcare and can't afford downtime -- been a long time since we upgraded from 4600 -> 5800.
Typically, starting with the Passive GW, just do the basic setup on the new appliance, import the config, swap it in, establish SIC and push policy (unchecking the "for gateway clusters...." option). Once policy installed, fail over and repeat process to replace the other 5800.
I have looked around and have not found any postings where anyone has done a conversion on live HA ClusterXL to ElasticXL. If there is an outage needed, I probably will continue with ClusterXL.
Any experiences, suggestions???
