That WAMP server is serving multiple virtual hosts. We now need to be able to migrate some services living behind those hosts under different stack versions. Some services are production ready and can be deployed with a more recent LAMP stack but some can't. I don't have an infinite number of servers to put all those services on but I do have the resources for containers. Reminder: when that WAMP server is down (which is an issue all by itself, the physical server has downtime as well), everything is down. Even static websites.
