We wanted to make sure that we are able to serve the entire WordPress community in a way that was sustainable for us as well. This meant that we had to put a cap on the number of migrations we could perform. We conducted a survey to ensure that the cap would fulfill requirements of majority of the community... and the results showed us that most WordPress users thought 5 site migrations per month was more than sufficient.
This means you can move each of the 5 sites any number of times, but you can only use the plugin on 5 sites per month. Having this cap makes sure that we don’t overburden our servers (since migrations happen on them). This isn’t the end though. As is the case with all great WordPress plugins, we’re always listening to know your requirements, and will keep improving the plugin to suit your needs.
