Please let me know if is ok? I will try to explain the scenario.

Site A

1 DD 2500 with 3 ES30 shelfs. The DD is empty.

Site B

1 DD 2500 with 1 ES30 Shelf. The DD is in production.

I need to move 1 Shelf from site A to Site B to have both sites with 2 shelf each. If I destroy the fs from Site A this will clean the data from the shelfs too? and have ready the shelf to be moved to site B? or could be another thing to do before?

I know I have to request a license migration for the shelf.

thanks for your help.
