I might be stupid sure feels so right now. Where are Xforms stored and how do I export the form (not the data that you can do with Client tools).
Actually there isn't any option to export just an XForm. What you can do is to simply export a page using the XForm you wish to export. The XForm will be included in the export package together with the page.
Then import that page to the new site, and the XForm will be imported as well. Then you can just delete the page, the XForm will still exist on the site new site.

Don't forget the Export/Import tab in the new XForms editor in R2.
Thanks for the answers. Just after I wrote this I thought of the export page/imort page would work. ctrl + shift c will be noted.
