Abstract
In one aspect, an example methodology implementing the disclosed techniques includes creating, by a first site of a volume that supports active-active bidirectional replication, a local copy of the volume, the local copy of the volume configured to be active. The method also includes enabling, by the first site of the volume, bidirectional write input/output (I/O) mirroring with a second site of the volume. The method further includes, by the second site of the volume, creating a remote copy of the volume, the remote copy of the volume configured to be passive, and enabling bidirectional write I/O mirroring with the first site of the volume.
