vSphere Replication 8.2 and earlier prevents you from resizing the virtual machine disk files during replication. If you did not use replication seeds during configuration of the target disk, vSphere Replication deletes the target disk when you stop the replication.
To resize a virtual machine disk if you did not initially use replication seeds, you must perform a recovery, resize the disk on source and target site manually, and use the target disk as a replication seed to configure a new replication.
- Recover a virtual machine.
- Stop the replication.
- Resize the disk on the source site.
- Resize the disk of the recovered virtual machine on the target site.
- Unregister the recovered virtual machine on the target site, but do not delete the disks.
- Configure a replication by using the disks of the recovered virtual machine as seeds.
