Convert single selection field to multi selection field


  • Used Zammad version: 5.2
  • Used Zammad installation type: Ubuntu Package
  • Operating system: Ubuntu 18.04
  • Browser + version: Chrome (latest)

I don’t know if this is something that is supposed to be possible or not.

Expected behavior:

  • Go to object “format” dropdown and switch object from single selection to multi selection.

Actual behavior:

  • Other object types unavailable.

Steps to reproduce the behavior:

  • Upgraded from 5.0.3 and wanted to use the new multi-select option for certain objects for more detailed data, but don’t want to lose historical data in current single select objects. Want to convert the single select to multi select.

As our documentation points out you cannot convert / change existing object types.
You’ll have to use a new one.

In case anyone is seeing this after the fact. I did actually find that reference in the docs and created the following feature request:
