As I just wrote on the wiki [1], upgrade through the lifecycle of Debian
stable is generally not a problem. What's painful is from one Debian
release to another (ie: upgrading a rabbitmq-server cluster for example,
is noticeably painful). Though you don't really *have* to upgrade, you
could migrate your workload to a new Debian release deployment.

Of course, you'd need more servers to do that, but at the same time,
after 3 years of production, you probably aren't against a refresh of
your infrastructure.
