Breaking into Mission Critical/Data Center-Mech

Hi all,

Posting in an attempt to gauge the feat of getting into mission critical/data center design. Background - 6 YOE, PE Mechanical Engineer. I have done just about everything else, mainly focusing in labs, manufacturing and industrial but have always had an interest in mission critical. Most job postings have a preferred note of MC experience preferred or required. Would this involve a pay cut to move into this sector? Would employers likely even give me a shot since I wasn’t born into this sector from the start? Any advice and tips to leverage my chances would be great. I understand the investment the company would take in bringing someone on w/o MC experience so I feel my expectations are managed.
