How do you switch EHRs without losing data?
You switch EHRs without losing data by keeping your current system live as the source of truth, running the new EHR in parallel, and migrating data in stages with a final backfill at cutover, rather than a single risky bulk move. Orion follows this model: nothing migrates during the pilot, and when you go live, your data moves in stages so nothing is left behind.
Data loss happens when clinics attempt a big-bang migration, exporting everything at once and hoping it maps cleanly into the new system. Running in parallel avoids this: your old EHR remains authoritative while you validate the new one, so there's always a complete, working record.
Orion's switch is staged. During the parallel pilot, zero records are migrated and your current EHR stays the system of record. When you commit, Orion migrates in stages with a final backfill to catch anything recent, and keeps a clean exit available throughout. You switch on proof, not hope.
