So the short of it is that my organization is doing a complete storage refresh at both our prod and dr sites.  What I am specifically after is any insight as to migrating data from my existing 20K to my new 10K  and what the process will be like.  Also, we are adding a vplex to our prod and dr site and want to know what potential gotchas there might be?  We do have professional services engaged but not until we get closer to moving stuff around will professional services be around.  Did i mention that we have an as400 as well?

Thoughts?
