Error upgrading to v16 from v15

Hi,

We are upgrading from v15.6.1HF396 running on SQL Server 2008 to v16.7.2 running on SQL Server 2016SP2.  We already have a v16.7.2 brand new community up and running fine, almost empty that we created before moving real communities, just for testing purposes.

The error is shown after Datasource creation in v16 SMC and the system detects an old database version and ask to run upgrade scripts.  We click yes and the we receive the following error: 

We have check everything, we have re-run upgrade and maintenance scripts from v15 SMC, stopped the eB service, stopped the eB Package and move again the database from SQL Server 2008 to SQL Server 2016SP2, but the error persists.  Do you have any idea whats is going on?  This is the error logged at SMC:
