[rabbitmq-discuss] Fwd: Recovery and Upgrade Path

[Alexis Richardson]

With Estaban's permission, I am forwarding this to the list.

Estaban I think your own suggestion is reasonable but you could also
look at our Windows service for that platform.

Re Erlang, think of it as being like Java.  You won't upgrade it very
often.  Read the RabbitMQ release notes for upgrade recommendations.

Hi Alexis -
Thanks for the reply.  So yeah I was wondering if I just create a bat
file (and shell script) on Windows Server/RHE server so if the box
ever crashes or gets a reboot that RabbitMQ will come back
automatically.  That is what I was thinking but wanted to know if that
was the best way.
Next is - yes - what is the best (and read easiest) way to upgrade and
I'm thinking to remove the old version completely and reinstall.  But
the reason why I ask is - on Red Hat - do I need to upgrade Erlang
first?  Its included in the Windows install so no worries there.

Thanks so much for your help - and sorry if I sound like I'm new. Its
only because I am.
Cheers
