[rabbitmq-discuss] Upgrade Erlang only with Persistent queues

I forgot to tell we are using Windows 2008 Server.
I firstly shut down RabbitMQ, killed the epmd.exe process.
And then I replaced Erlang folder and ran install.exe -s.
I also changed the registry to correct the path to erl.exe (I found 3 places).
After doing all of these, I tried to start RabbitMQ service and it just crashed.
Is there anything I missed?

If you publish messages as persistent and queues are durable, you will not lose any messages upon server shutdown. It's a good idea to back up your Mnesia directory (often located at /var/lib/rabbitmq/mnesia on Linux) before upgrade.
