What happens to unclassified work items when you set a default classification level in a Jira space?

[Sveinung Solhaug]

We want new work items to have a spesific classification level, but don't want to touch existing work items (not the items that are unclassified either).

Is that possible?

Welcome @Sveinung Solhaug 

That is work item security. You need to create a new security level for that work item security scheme. Security level field also needs to be added to the Create screen as well.
