Error importing data: java.lang.IllegalArgumentException: Unsupported field encountered: binary

[Nic Brough -Adaptavist- · Accepted solution]

That suggests a plugin has provided a field, so you have data for it, but the new version doesn't support it.

Go back to your old instance and find the field called "binary" - what type is it?

Hi Nic,

Even we faced the same issue. Can you please let me know the exact resolution.

Many thanks in advance.

I'm trying to restore JIRA using a backup from other instance, I'd faced another error before this one, probably cause the plugins used on the old instance. After isntall the plugins I received this exception.
