The Online Migration service template enables you to migrate a host in an online state through Ops Center Protector, access the switch management server to obtain existing fabric configuration and zoning information when allocating new volumes to the host, and then update the zoning information.
Prerequisites

Storage port aggregation
The service determines the migration source path volume by using a combination of the specified source and target storage ports. However, when the migration source host group is shared between servers in some cases and not in others, there is a high possibility that the migration path will be different than what the user intended. In this case, it is not possible to combine a group of migration source storage ports into a single migration destination storage port. In most cases, the storage port is divided to increase fault tolerance, so if you are migrating to a configuration without, or with reduced, fault tolerance, you should not run a migration until you understand the possible issues involved.
