Delete trigger during ECC Upgrade

Hi Experts,

We had set up SLT server to replicate data from ECC to HANA. We are going for ECC upgrade. While doing ECC upgrade in dev enviroment we are getting errors that about the triggers existing on the system. As per the SAP note 1620618 it looks we need to delete the triggers that were set up on ECC. Any idea how to handle the scenario. Does Reset Trigger works in this scenario. We don't want to load or replicate tables again. Can you please provide the details steps that needed to recover after deleting triggers on ECC. Appreciate your help.

Thanks,
