  • The host must have write access to both the source datastore and the destination datastore.
  • The host must have enough free memory resources to accommodate Storage vMotion.
  • The destination datastore must have sufficient disk space.
  • The destination datastore must not be in maintenance mode or entering maintenance mode.
