Suggestions on MAJOR Server Room Renovation

I have a project of major server room renovation (the server room looks a lot like the before pics in “Watch a server room cabling nightmare become an organized dream”)

Cables are disorganized, servers are all over the place…there is limited space…just imagine the worst.

So its time to overhaul the current room. We’re not moving it, just “updating it”.

Does anyone have any suggestions at all on conducting major renovation to a server room?

Thanks in advance.
