We have migrated our one environment from Appian 7.2 to 7.6 to 7.7 by using same old database used for Appian earlier from version 7.2. We had also faced the issue related to data type during the migration from 7.2 to 7.6 in which support provided script to run command
-> clear-external-type-id.bat false.

Currently we are unable to download the XSDs and not able to publish the CDTs which is not allowing to verify the datastore mappings.
error seen like
The data type could not be saved: null (APNX-2-4047-008).

Any solutions ...
