There is a problem copying adaptors after upgrade from 7.1.1.x to 7.1.3.1 and later. Some adaptors were updated for version 7.1.3.1. If you upgrade to version 7.1.3.1 and then attempt to copy a adaptor that was created before the upgrade, an error is reported:
CRRBF0789I: A valid Adaptor Template Identifier must be specified.
Workaround: before attempting to copy the adaptor, do the following: open it, rename it, and save it. You can also open the adaptor, copy the adaptor's content, and create a new one.
