BGP / JunOS question

We have datacenter A which is running MX104's and has a /22 subnet (2 of the /24s are in use here).

We have another datacenter B which is similar config, using one of the /24's from the above /22.

We're decommissioning datacenter B and bringing the hardware to the office to use in house. The problem is we no longer have our BGP guy. I know anout about JunOS to navigate and change/break things.

What am I looking at to make that /24 work at the office assuming we have internet with a static IP? Do I need to involve the office ISP to peer with them or anything? Or if I change the ip in the router to the new static ip of the office and update the neighbor AS, will it just magically work?
