-----------------------------
Summary: 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.
