I need a guide to upgrade existing BE6K to a new BE7M, customer is planning to make the upgrade and I can't find any migration documentation for it.
Because there's nothing special around this HW migration, use any of the available options, DRS, vMotion, etc.
I have never done a hardware migration before, can you please brief a little about it or if you have any awesome video of yours, can you share here
if you are doing upgrade as a part of this migration then you use Cisco PCD. Here is the URL for video:
Make sure read release notes and upgrade guides for PCD and UC Applications.
