How to change tracker field types
Until Tiki6, it was possible to change the Tracker Field Type in an existing tracker. This was convenient, but could lead to issues because the data types can be very different. Ex.: convert from a text field to a category picker.
Starting in Tiki7, the interface no longer permits this. But if you have server access, you can do it manually:
Data corruption possibleProceed at your own risk.
While some types can be exchanged quite well, such as converting a text field to a text area, many conversions will cause data corruption and possible crashes as the data struture varies from field to field.
With adminer or similar, go to tiki_tracker_fields and look for the field "type" and change the value.
Tiki 12.x: A "Change Field Types" preference (default off) is available from tiki-admin.php?page=trackers
