You may be happy to learn that Kobo will officially replace Pocket with Instapaper by the end of the summer. It was just announced yesterday.
You should be able to export your Pocket data into Instapaper. I couldn’t get the export feature to export more than one entry, however, so I ended up manually transferring the bookmarks.
Edit: But I was given this link today which should make transfers easy.
