Define what work may be needed to get OpenMRS Platform 1.11 running underneath OpenMRS 2.x

We hope to use OpenMRS Platform 1.11 (or possibly 1.12) beneath OpenMRS 2.2 (targeted for March 2015). For this to happen, we need someone to test running OpenMRS 2.2 (snapshot) with OpenMRS Platform 1.11 underneath it and then enumerate what problems exist (i.e., how much work will it take to get it working).
