I've been working on importing some documents using the Migration API beta. I'm not signed up to the private beta (but I have joined up to the wait list) but have been using the demo key as the documentation explains.
I've created a few documents and published, then created some test ones and deleted them, then finally ran a full migration run for a single document type (approx. 250 documents), but now the Migration Release page doesn't show the documents.
I know the documents exist as I stored the document ids returned, and if I try to recreate a new document with the same uid, I get an error message stating the document already exists.
Is there any way to either see the migration release, or delete the existing documents so they can be recreated into a new release?
