Several years later, Railo was no longer being updated, and its website was shut down. The last post on the Railo site in mid-2015 mentioned a new (and perhaps unauthorized) fork of Railo 4.2, called Lucee. The Railo website then disappeared in mid-2016.
Due to the apparent demise of Railo and the continued need to support my CFML applications, I moved all of them back to Adobe ColdFusion 11.
Unbeknownst to me, Lucee was already gaining more support and has now taken the place as the leading open-source CFML application server.
While I don’t have any concrete plans at the moment for migrating my apps from CF 11 to Lucee, it’s good to know that I have options. Also, anyone considering moving from Railo to Lucee may find this article helpful, as this early adopter has already found some of the problems when migrating from Railo to Lucee.
