We are migrating from Server to Cloud, and we are not migrating anything in the archive. However we would like to be able to export all issues in the archive to have as a backup for referencing. Under Issues > Archived Issues, I can see them all but if exporting from that page I only get limited info.

The user requirement behind having the archived issues exported is so we can reference it to see why certain decision were made (as some devs might not work with us anymore). So the comments would be needed as well.
I can see I can access further information through calling, but wondering if there is a version for ALL archived issues:
