Changing cluster configuration

In a two node cluster, is it possible to change from a Active-Passive configuration to Active-Active without completely reinstalling?

ThanksI do not think this is supported. At any time, there should be only one node owns cluster resource such as physical shared disk, IP address, cluster group, etc. This node is called the active node. When you failover to another node in a cluster, all owned resources in the active node will be switched, too.sql
