Abstract
In one embodiment, a new storage system is connected to an old storage system destined for replacement. Prior to starting online data migration, remote copy configuration information from the old storage system is migrated to the new storage system. The aforementioned allows either the new storage system or the old storage system, depending on configuration, to maintain an operational remote copy function with another storage system during the online data migration. The old and new storage systems can be primary storage systems located in a local site. The old and new storage systems can also be secondary storage systems located in a site remotely located from a local site.
