    If both Clusters are in the same data center, you could do a "live" or vMotion migration if this is the case.   If the VM is powered off it may be migrated regardless of the data center.

    This is possible however there are a lot of caveats and pre-requisites to check first.

    The clusters must be managed by the same vCenter server

    As posted above they must be in the same Datacenter object

    If you are pre vsphere 5.1 and enhanced vmotion then the clusters must have access to the same datastore

    The vMotion network must span the clusters
    Processors of the hosts in the new cluster must match (or have evc on to seem like they match) the existing host

    If you are using a Distributed Switch, then the portgroup must span across the clusters

    If you can tick all those boxes (or rule them out as they aren't applicable like DVS) then you can simply vmotion as normal.

    I have done this several times. I fully agree with Chris.

    In addition to that, you need to consider what impact can be there on destination cluster due to CPU/Memory. There might be chance that migration of one VM from a cluster can lead to over commitment of resources on other cluster. You need to consider HA/DRS/DRS rules constraints . (Ex. Some soft DRS rules may be violated )

    Plz make sure you satisfy all above requirements.
