I've just looked through your support case and looks like transferring any database from R2 to an earlier version of SQL Server is not supported by Microsoft:
The database “VeeamOne’ cannot be opened because it is version 661. The server supports version 655 and earlier. A downgrade path is not supported.
Could not create new database ‘VeeamOne’ CREATE DATABSE is aborted.
To resolve this issue I would suggest to create a brand new database on your production SQL Server to host Veeam ONE performance and configuration data, should help.
