What do we mean by fallback?

Fallback is the process of migrating users from QMF Version 7.2 to an earlier release. If you are interested only in fallback, turn to Fallback. Cleanup is described in Step 36--Clean up after install and is not discussed here.

Version 3 (and later) forms and the forms for earlier QMF versions have different internal representations. When one of the earlier forms is converted to a Version 3 (or later) form, it no longer can be used with an earlier version of QMF.

Applications developed to work with QMF Version 2.4 (or earlier) forms might also not work if they reference the object level in the header record or break field numbers.

To prevent users from accidentally converting a version 2 or earlier form to a Version 7.2 form (a mistake a user might make by replacing the old form while running under QMF Version 7.2), you can save both the earlier version and a Version 7.2 version with different names until it is clear that one version is no longer needed. For example, the following commands convert work area forms to Version 7.2 forms:

SAVE FORM AS FORM1
EXPORT FORM TO FORM2

If your installation falls back to the earlier QMF release, urge your users to recreate their Version 7.2 objects under the earlier release before QMF Version 7.2 is withdrawn.
