Migration of BES from LN to Exchange

I am currently running a project to migrate users from Lotus Domino to MS Exchange.  One of the many migrations is to move our Blackberry users from Lotus Domino BES to the Exchange BES environment.

We are currently running a Proof of Concept lab, where we have both the BES environments and I am looking for a tool to assist the migration of users from one to the other.  We are using the Quest tool to migrate the nsf mail files, but I am wondering if anyone has had experience of migrating the Blackberry devices.

Mindmaps for web and Android

I am looking for a service to be able to create mindmaps on my Android tablet, as well as enable me to view and edit these on the web.

The maps should sync with the tablet when I load it, or allow me to edit them offline.  Does anyone know of such an app?
