Thank you for reply.
I do not understand details from which SDW4.1 is selected.
Maybe, it is thought that SME3.2 and SDW4.1 were the latest release at the timing of the introduction.
My customer wants to version up a version of ONTAP 7.3.0 or later.
Do you think that is necessary to give all version ups?
Thanks and regards.
