vSphere Replication prevents you from resizing the virtual machine disk file during replication. If you used replication seeds for the target disk, you can resize the disk manually.

Procedure

  1. Unconfigure replication on the virtual machine.
  2. Resize the disk on the source site.
  3. Resize the target disk that is left over after you unconfigure replication.
  4. Reconfigure replication on the virtual machine.
