    Problem with data type compatibility: radio button list, drop down, checkbox list

    I am migrating from Umbraco 7 to 8 and 9 and I have problem with data type compatibility.

    Basically in v7 data types such as radio button selection, checkboxes, dropdown values were stored as data type value ids or array of ids, eg.


    In v 9 they are stored as literal values or arrays of literal values eg.


    So the result is - after migrating - that the values are present in the database but do not show in the CMS.

    Do I really need to convert every content to use the literals?

    Or is there any way to keep the previous notation of the values eg. as data type ids in v9?

    I have found the issue why the data is not showing up in the CMS after the migration. This is true only for Radio button list values. Checkboxes and dropdowns are showing well.

    Yes, the property data of type Radio button list in Umbraco 8 is stored as string (instead of integer id as in Umbraco 7).

    I have reported the issue with Radio button list values here:

    And I also added there a quick fix to the issue.
