Good tool for Migration to SharePoint from Notes
Quest Notes Migrator for SharePoint (NMSP) can be used easily. You just have to define fields that will be used from Lotus Notes, those from the SharePoint site (local or remote as we can use Web Service connection), map Lotus Notes fields with SharePoint fields and that’s all! It is how the simplest mode works.
NMSP is able to preserve data like creation date or security settings (it preserves equivalent of authors and readers fields and Lotus Notes roles). You are able to create SharePoint list based on Lotus Notes fields with this tool. Furthermore, you can also easily modify data during migration by using formulas (with Formula language) on fields or map Lotus Notes users to SharePoint users easily.
NMSP is in fact a pack of tools: NMSP Designer, NMSP Console and NMSP Web Service. Jobs creation is done with the Designer. Console is used to analyze and have an overview of applications in Lotus Notes but also to manage, organize and schedule jobs execution. Each tool can be installed without installing complete pack. Installation of these components through wizard is quite simple and some steps are really useful. Web Service is used when it is not possible to use NMSP Designer on the SharePoint server.
Licensing model is easy to understand: one license is required per source database replica. With a lot of databases, migration can be expensive but losing data can be even more expensive. You can also develop a tool but it will also be expensive as there are a lot of important functionalities.
Last but not least support is reactive and sends every time feedback about issue, question or suggestion you send.
