Can QMM mail and PF agents run on Exchange 2000/2003 Active/Active Exchange cluster?
According to QMM Release notes:
"Migration Manager for Exchange supports Windows 2000/2003 cluster servers only if no more than one Exchange Virtual Server is running on a single cluster node. Migration Manager detects such systems and configures agent services for automatic failover together with the Exchange services."
Quest mail agents would run in an active/active configuration; however, will stop functioning in case failover occurs and single node has two virtual Exchange servers.
As a general recommendation Microsoft has the following statement about Active/Active cluster configuration:
"Microsoft does not recommend the deployment of Exchange 2000 servers or Exchange 2003 servers in an Active/Active clustered environment. Additionally, Exchange 2000 and Exchange 2003 are supported as Active/Active in two-node clusters only. Clusters that have more than two nodes must be Active/Passive.
