Move Database from 2008 R2 to SQL 2016


I am still running Change Auditor 6.8 on mirrored SQL 2008 R2 and I want to move this to SQL Server 2014 SP1.

I am proposing to run the Change Auditor 6.8 SQL setup on the new SQL 2016 Database, export the custom searches and run the dbmigration tool. 

Is this the best process or could someone please provide the recommended steps for this, and any problems that have been seen when doing this? A link to any reference doc on how to do this would be good.

I need to do this to become compliant with the SQL server version and then upgrade Change Auditor to 7.x later this year.
