Hi Team , In order to meet a certain security standards of Organisation and business requirement , we have to import external jars to make use of libraries that meets our needs . We have searched for any best practices in PDN in order to perform any Rollback if required , however couldn't find any concrete results for the same  . This request is to get an expert assistance for the JAR Rollback . We understand that taking a DB backup and restoring is one of the options , however since our environment/servers are shared across multiple Applications , we would like to understand,  if there is any specific steps to rollback ONLY  the imported JAR (Deleting JAR instances from any particular table etc.)
