I have been tasked with maintenance of our ActiveMQ install on Windows, after
its previous maintainer left the company. Let me say, up front, that I am brand
new to it and am working to come up to speed on it, so please bear with me, if
I should sound clueless.
We are running version 5.1.0. It would appear that our installation is
virtually an out-of-the-zip install, with only two minor edits to the
activemq.xml file (I diffed our 5.1.0 directory tree against a pristine
download of it):
<managementContext>
<managementContext createConnector="true"/>
</managementContext>
whereas in the pristine copy it is set to false, and:
<!-- <route>
<from uri="activemq:example.A"/>
<to uri="activemq:example.B"/>
</route> -->
whereas in the pristine copy this is uncommented.
I've been tasked with upgrading to 5.3.1 and being able to roll back to this
version if need be. Looking at the changelogs for the version after 5.1.0, I
see that much has changed.
My first question is this: if I make these same two changes to the 5.3.1
configuration (the first in activemq.xml and the second in camel.xml, since
that's now split off), is 5.3.1 a drop in replacement for 5.1.0, that will
simply 'just work' in the same way without any of our stuff that uses it
noticing any difference at all?
Secondly, if we ran into trouble, could I just shutdown the 5.3.1 service,
restart the 5.1.0 service and just be back in business again?
Thank you, in advance, for your time and comments.
