A data management method and system for migrating a data volume from a source array to a destination array includes receiving an indication of a source volume to migrate from the source array to the destination array wherein the source volume comprises a clustered volume associated with a plurality of cluster hosts. A path-flip is performed by the host multipath module, to switch the paths between source and destination array. This switch is done in a seamless manner, without disrupting host I/O. The path-flip includes transferring associated metadata from source to destination and can be performed even in clustered and/or multi-host environments. Sanity timers are built-in to ensure that the path-flip completes within a stipulated time-frame and, if not, the path-flip process is aborted and I/O is resumed without any disruption.
