JPD date field migration

[Barbora Vacková]

How can I migrate a date field from JPD to Jira? I created a JPD date field with the same name and type as the one we use in Jira, and I want to migrate this field into the original Jira Start date.

However, I’m getting this error:

The Jira Start date is also a Date field, so I’m not sure what is causing the issue.

The only thing that comes to mind is this: when I try to display the JPD “date field” in Structure, it doesn’t appear as a standard date field. Instead, it shows in this format:

{"start":"2026-01-01","end":"2026-01-01"}

Is it possible that this is the reason it cannot be mapped?

And if so, when will the JPD “date field” behave as a regular date field in Jira?
