A system and method for data lifecycle management. In one embodiment, data
is migrated from a source physical volume at a primary storage system to
a target physical volume at an external storage system. The data from the
source physical volume is copied to the target physical volume. When a
request is received at the primary storage system from a server to access
the data in the target physical volume, the server is added as an owner
of the target physical volume, sent location information of the target
physical volume, and allowed to access the target physical volume
directly without passing through the primary storage system. The volume
for migration may be determined based on not having been accessed for a
specified period or having been specified by a user or an application to
be migrated. Extents, objects and files may also be migrated.
