Hi Shafeena, Could you confirm if after your migration, you did not change the values of your OAuth2 credentials in your property file? If you did not change anything in your property file and if the user still exists in your AdWords account, then it should have worked in v201802 API version.
Based on the error description "The OAUth client was not found", it seems that the API user is not existing (or it has been removed) in your manager or client account, or the client ID was deleted in the Google API Console Credential <https://console.developers.google.com/apis/credentials> page. So I can further investigate this, can you provide to me your complete error logs, clientCustomerId and the email address of your API user via *Reply privately to author* option?
