Develop a Product strategy for a health tech startup

I am building a Software platform an online solution provider for the healthcare industry. I recently acquired an orthodontics software package, OrthoPlus, and a dental software package, DentalOnline, and is in the process of merging the two solutions into one online platform to create a more holistic patient and provider experience. MB's market research has shown that the majority of dental offices do both traditional dental work and orthodontic work but keep those patient records separate—solely because there isn't a solution that has accommodated both needs. In addition, many dental offices also perform cosmetic dentistry and often maintain separate records for those patients and procedures.
I want to build a shared new patient on-boarding feature as well as an administrative tool focused on helping providers (dental/ortho offices) migrate to the new joint system.
