Because VS2 and VS6 cannot co-exist in same cluster.
I would like to migrate LUNs of any of the data from VS2 to VS6 with different storage attached.
If possible without downtime.
Any hints or best practises?
Late answer but my buest guess is to use host based tool like storage vmotion for vmware and powerpath migration enabler for other supported hosts. Some unix/linux volume managers are able to do similar stuff while volumes are online.
