Exchange 2007 provides support for two different parts of clustering technology: SCC (Single Copy Cluster) and CCR (Cluster Continuous Replication). With the newly introduced support for Exchange 2007 migrations, does new version of QMM 8.0 support SCC and CCR clustering in Exchange 2007?
Please refer to QMM Quick Start Guide.
As per the Quick Start Guide document:
"Migration Manager supports only Single Copy Clusters (SCC) when working with Exchange 2007. To learn more about SCC, visit http://technet.microsoft.com/en-us/library/bb124721.aspx."
CCR clusters are not supported.
