how to modify a field type after creation

[GASPARINI-COZ]

I have created a field with select list (multi choice) instead  select list (single choice).

how can I now simply update this type?

Unfortunately this cannot be done. As you can imagine this could become very challenging should Issues with data exist.

thank you very much for the reactivity. I will create a new field and delete the old one

@GASPARINI-COZ  , The simple way is to create a new custom field of the same name in type select list (single choice). Replace the same in the corresponding screens. Unfortunately you cannot directly update or change the current one.

Hi @GASPARINI-COZ 

This is currently not possible in the application.

The way Jira reads and stores values for different field types makes this difficult. For example, some are stored as string while others are stored as options which are mapped to the actual value.

Do check here for an official Atlassian answer or to raise a feature request: https://jira.atlassian.com

Hope this helps.
