Hi Tanu,

Thanks for quick response.
Could you please share more clarification on the below:

Will the ATF plugin be removed after cloning from Production?
Tanu: It can be. If the ATF Test Generator and Cloud Runner plugins are not installed in the Production instance, cloning Production to Development or Test will remove those plugin configurations from the target instances.
Shikha - ServiceNow documentation says there is a property that is disabled in PROD so that the ATF are not run accidently on PROD. So, when we were are not going to run anything on PROD, why we should move the update sets to PROD? I want to understand the concept behind it. If you can share any documentation link , that will be great.

Are ATF tables and test records overwritten after a clone?
Tanu: Yes. During a clone, the target instance is overwritten with data from the Production instance. As a result, any ATF tests created only in Development or Test will be lost unless they have been promoted to Production or backed up beforehand.
Shikha : I know we can make preservers and exclusions on PROD for ATF tables. But before doing anything, isn't there anything OOB that can help me save these tables date? any doc link will be helpful, if you can share.
