anonymous_user_id field getting auto-populated with different value after data port to Ficus.4

[Anand R.C]

Hello,
We ported data from an earlier release to Ficus.4. This included data relating to ORA file submissions.

The student_anonymoususerid table had anonymous_user_id value populated for a particular (user_id,course_id) combination. After porting, one more record is getting added in this table with a different value of student_anonymoususerid for the same (user_id,course_id) combination when student loads the ORA problem.

This anonymous_user_id value is the key for accessing a file on AWS S3. Now since the latest record in the table has a different value for this key, the file cannot be fetched from AWS S3.

It seems like moving from one server to another (probably) somehow changes the value of student_anonymoususerid generated.

Can anyone please point me as how this anonymous_user_id is getting generated. And how can we ensure that the same anonymous_user_id gets generated after moving to a different server.

Any help is appreciated.

Thanks in advance

Anand
