Hi Viraj,
You might be lacking the needed API functionality on your new okta.com tenant, which is a paid feature.
In oktapreview.com most of these features can be activated free of charge for testing purposes.
Please contact Okta support to check if you are entitled for this functionality in your .okta.com tenant.
