I wonder about this. Let's say:
Step 1: I deploy custom metadata from Sandbox to Production.
Step 2: Then somebody adds records to the deployed metadata in Production. This will create a difference in the records between Production and Sandbox.
Step 3: Now let's say I make some changes to the records in the Sandbox and deploy them to Production again. Is this going to overwrite the different records that were added in Step 2?
If so is there a way to preserve these records?
