Convert single selection field to multi selection field

Infos:

  • 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.
