Is there any automatic way to delete the discrepancy/tasks between test and dev2 environments

Summary:Using implementation package , we are trying to migrate the code from test to dev2 however by comparing these implementation packages between dev2 and test we found that dev2 has additional setup data for many tasks compared to dev2. IS there any way to automatically delete these additional discrepancies from dev2? So that we can have the same configuration across both test and dev2. 

Also if the same configuration is present for a specific task in both the enviroment, after doing a import using implementation pacakage does the configuration remain unchanged/it will create a duplicate ?
