Hello Guys

I have an EMC Isilon with OneFS v7.x.x in my environment and I am looking to
also setup a cluster of OneFS v8.x.x.
Correct me if I am wrong;

1. I can remove the HDDs in my v7 and insert them my v8 without any problems.
I just need to add and format the HDDs.

2. It is not necessary to upgrade the HDD firmware in order to use them in v8.

3. Is it possible to also format and use HDDs in v8 in a node with a lesser OneFS version like v7.

In a nutshell, I am trying to find out if I can use same HDDs across two different versions of OnefS
(v7 and v8 in my case).

Thank you.
