You may wonder if you install LiteSpeed whether you need to migrate all users to LiteSpeed and if installing LiteSpeed is a time consuming job. Fortunately, the LiteSpeed webserver is a drop-in replacement for Apache. This means that it will act similar to Apache and uses its configuration. No per-user migration is required in order to keep the websites online. LiteSpeed claims that the convertion from Apache to LiteSpeed only requires 15 minutes.
The websites will remain functional and static files will have performance improvement. To benefit from the speed improvement we recommend to install a LiteSpeed plugin for every website. This plugin communicates with the LiteSpeed server and is the magic tool to create a blazing fast website. You do not need to do this immeditiately. The websites will run like normal after installation of the LiteSpeed webserver.
When you have installed LiteSpeed, you can change between using the Apache webserver or the LiteSpeed webserver. This feature allows you to switch with one click and only requires a minute or so. This feature is useful in case you want to test the differences in speed between LiteSpeed and Apache.
