Few days ago I got the following error while trying to export SQL database to a bacpac file:
Connecting to database 'AXDB_copy' on server 'localhost'.
Extracting schema
Extracting schema from database
Resolving references in schema model
Validating schema model
Validating schema model for data package
Validating schema
*** Error exporting database:One or more unsupported elements were found in the schema used as part of a data package.
Error SQL71626: The element Certificate: [cert_name] is not supported in Microsoft Azure SQL Database v12.
The fix is to open SQL Management studio, create database copy, expand "
<myDBcopy> -> Security -> Certificates" and delete all certificates. After this export copied database to a bacpac file.
