Compare Farms and Web ApplicationsIt’s common for an administrator to have several SharePoint farms running on similar hardware, but their performances vary due to different configurations. In those situations you might like to find out how one farm is configured differently from another, so you could tune its performances.
Comparing farms can also be critical in cases where your organization has multiple farms for different purposes, e.g., DEV / Production / Q&A / Staging Farms. Documentation Toolkit for SharePoint enables you to create configuration snapshots of each farm. Once you export snapshots to files, you can compare the snapshots. It does not matter if farms are connected or part of the same IT system—the comparison is made solely between the files.
