Notes Migrator for SharePoint 4.5 is getting pretty darn close! We are very near to RTM and should be Generally Available shortly after that.
The following document is a new Installation Checklist we created to help people plan their installation in advance of downloading the full user guide. (Of course everyone will read it eventually, right?) With two clients and three deployment options we wanted to clarify what choices people have as they plan out their environments. Aside for the Desktop client, everything should apply to the current release as well. As always, your feedback is appreciated.
