Like others have said, snapmirror if possible:
CDOT source? snapmirror
7mode source with 64bit data (aggr,vols, AND snapshots)? 7MTT or snapmirror
7mode source with 32bit data (aggrs, vols, OR snapshots)? FLI, or upgrade to 64 bit and use 7MTT or snapmirror
Also review the SAN host remediation guide
