Hi Community, I have upgrade my application from 6.10.4 version to 7.2.0 version and resolved all the issues during the upgrade. Now I am trying to test my application and got some conflicts. Please find the below conflicts. Please find the below conflicts:- 1. Error occurred on rollback database transaction. Cannot invoke a rollback operation when the AutoCommit mode is set to "true". 2. See the below conflict. JdbcDataStore::execRetrieveQuery caught SQLException without error number; broken JDBC driver?

Some where I saw that I need to use Tortoise SVN to resolve the conflicts during the upgrade. I haven’t used it before. Can you please let me know the steps to follow to resolve the issues. Thank you.
