I've switched domains all the time (CAD/CAM -> Medical Imaging -> Genomics -> Web Development -> Internet Security -> VR -> Fintech), things I've found helpful:
1. Ask a lot of questions at the start. People know you've switched domains and will tolerate dumb questions for a while.
2. Don't ask the same dumb question twice.
3. Read a lot to get into the new head space. Set up google alerts for your company and its competitors. Join forums dedicated to your new tech and domain.
4. Offer learnings from your old domain, humbly. "At my last gig, we approached this <method>. May not apply." This shows everybody you have things to offer but you are just getting your sea legs.
5. LEAVE THE OLD JOB. All of the above things you did for your old gig. Stop doing them, you don't have time anymore.
