Assume that you register a Microsoft SQL Server 2014 database as a data-tier application (DAC) in SQL Server Management Studio (SSMS). The instance ID for the new DAC package (DACPAC) is different in the sysdac_history_internal and sysdac_instances_internal system tables after you register.
Note Both tables should have new records that have metadata for the newly registered DACPAC. The instance ID in both tables should be the same, so that you can join the two tables to track history for the different DACPAC.
