Abstract
A method to provide resiliency with a destination volume in a replication environment is disclosed. Data from a source volume, such as a primary volume or a secondary volume in a replication relationship, is migrated to the destination volume. A snapshot representing data on a source volume is generated. The replication relationship between the source volumes is broken, and a new relationship between a source volume and the destination volume is established. A delta of data between the snapshot and one of the volumes in the new relationship is generated. The delta is sent to the other of the volumes in the new relationship.
