If you have an existing perpetual license, you can use it infinitely, just as the license agreement stated when you purchased it.<p>We do however offer a switch to the new model if you like it and if you&#x27;re interested in new versions that your perpetual license doesn&#x27;t cover. If you do switch to the new model, you pay as long as you need to use a tool, and you always get the latest version.<p>IntelliJ Ultimate will continue to offer language plugins, nothing changes in this regard.
