I am planning to do online storage migration following below steps, it has one ldom.
  1. Remove 1 fc
  2. Assign the luns from the new storage
  3. scan the devices
  4. Mirror it ( dont know the command )
  5. Break the mirror and remove the old storage lun
  6. attach the 2nd fc.

Will this work ?
