How to approach moving offices within a national brokerage?

For context, I’m looking to make a move for personal reasons. I have been very happy in my role and I like the work I do and the people I work with, so I don’t feel the need or want to find a drastically different role.

I have recently been made aware that another office within my company (nationwide debt brokerage) is looking to hire someone at my level in the location I am hoping to move to. I am wondering what the proper way to go about starting that conversation would be without it seeming like I’m going behind the back of the producer I work with.
