Hi,
We made a hasty decision of upgrading our APEX development instance from 18.1 to version 21.1 over the weekend. Unfortunately, there were still on-going application enhancements in our dev instance and needs to be deployed to our Test and Prod instances accordingly.
However, when we try to export our applications from the dev instance (21.1) to our Test instance (18.1), it returns an error "NOT COMPATIBLE (Your export may contain calls not supported by your Application Express version.)"
Is there anyway we can export from the 21.1 that is compatible to the 18,1 version?
UPDATE:
Just wanted to add that the application compatibility mode is set to 5.1/18.1/18.2. This is in the version 21.1 instance where we do the export.

Regards,
Allen
