Policewomen with policemen S/Os

I've been in a relationship with my S/O for the past two years, we met in training.. We work for different services, which brings a host of issues with it.
The main issue is one/both of us (most likely me) will have to move eventually, in order for us to have a family.
Just wondering if anyone else has been in this position (or a similar position of being in the same profession and rank as your SO). I'd love words of wisdom and advice for keeping our relationship strong and moving forward.
