Third-party vendors offer products that help automate the process of reviewing your applications for compatibility with Domino 7 and Designer 7. These tools are geared towards businesses that need to migrate a large number of databases.
Currently, the most prominent third-party tool for helping ensure Notes/Domino 7 compatibility is Teamstudio Analyzer, (See http://www.teamstudio.com/solutions/analyzer-spotlight.html.) This provides a pluggable architecture that allows customers to buy only the filters they need. One such filter is Best Practices for Domino 7. They also sell filters to automate the scanning of code known to cause problems during an upgrade.
