Most companies have very heterogeneous environments where some machines are outdated and others are new. Usually, it's required to copy data from the old machine to a new machine that runs Oracle Solaris 11, and it's a perfect time to use an excellent feature named Shadow Migration. This feature can be used to copy (migrate) data through NFS or locally (between two machines), and the filesystem types that can be used as the origin are UFS, VxFS (from Symantec), and surely, the fantastic ZFS.

An additional and very attractive characteristic of this feature is the fact that a client application doesn't need to wait for the data migration to be complete at the target, and it can access all data that was already migrated. If the required data wasn't copied to the new machine (target) while being accessed, then ZFS will fail through to the source (original data).
