I am at the final step of upgrading a website from 8.2 to 9.0 i.e. migrating the analytics data from MongoDB to xConnect. I am using xDB data migration tool and following the guide provided by sitecore.
I have analytics data in MongoDB and all the connection settings and configurations are properly configured (as per the upgrade guide).
When I run the pipeline batches for migrating MongoDB data to xConnect, it runs fine. I can even see the migration operation in the verification database in SqlServer.
After the pipeline batch completes, I don't see any migrated data in the Sql Server in the corresponding database (i.e. the one which is supposed to hold analytics data). And, obviously in the Sitecore Experience Profile there is no data (a red label appears on top to indicate An error). This is the screenshot of the log file: https://i.stack.imgur.com/atRnZ.png
Any help or suggestions would be greatly appreciated.
