This weekend (02/24/12 – 02/25/12 19:00 Eastern [00:00 GMT]) we will be performing SP2 upgrades to the Europe Exchange 2010 Cluster: Della. Upgrade to Exchange 2010 SP2 will be performed on all passive nodes in Della. Upon successful upgrade clients will be moved from the active server to a passive node. . This upgrade is not expected to impact customer access however, there will be critical changes prior to the upgrade.
· New load balancer will be activated across the passive nodes.
· IP address for cas.della.exchangedefender.com will be modified to the new load balancer (Expected to be 188.8.131.52)
On Friday evening users on the active node will be moved to the passive nodes. The switch over from active to passive should be transparent to users.
Unfortunately BES services may be interrupted as BES does not detect and handle upgrades seamlessly. If BES service is interrupted we will work on restoring service after SP2 has been successfully applied.
Update 3:05 AM: Exchange 2010 SP2 has successfully been applied to DELLA.
