-------------------------------
Split out from AMQ-6099 into a stand-alone issue.
> Provide command-line utility to migrate KahaDB files to a new OpenWire version
> ------------------------------------------------------------------------------
>
> Key: AMQ-6103
> URL: https://issues.apache.org/jira/browse/AMQ-6103
> Project: ActiveMQ
> Issue Type: Bug
> Components: KahaDB
> Affects Versions: 5.x
> Reporter: Tim Bain
>
> Since the KahaDB code can currently only support a single OpenWire version at
> a time, there is no clean way to upgrade a broker to an ActiveMQ version that
> uses a new version of OpenWire if there are any messages in the KahaDB data
> store and you want to keep those messages.
> One thing that would be useful would be a command-line utility that could be
> run while the broker is offline to convert the KahaDB data files/indices/etc.
> from their current version of OpenWire to any other version. I expect you'd
> read the files in from start to finish using the code that corresponds to
> their current OpenWire version and write the messages out to a new set of
> files in the desired OpenWire format. Maybe you'd want to compact the files
> while you're at it, but that's certainly not a must-have.
