Hi Steve,<br>
<br>
There is currently no easy way to migrate the database.<br>
<br>
In general, it is advisable to use the same code which you first used
to create the exchanges, queues etc. on the new version of Rabbit to
reconstruct your setup.<br>
In order to migrate messages, you would have to use the rabbitmq-shovel
plugin, which would consume messages from the old broker and would
publish them into the new one (you must come up with a sensible
configuration, depending on you setup).<br>
<br>
Hope that answers your question.<br>
<br>
Rgds,<br>
Vlad.<br>

<p class="MsoNormal" style="margin-left: 0.5in;">Upgrading <br>
========= <br>
The database schema and the format in which persistent messages are <br>
stored have both changed since the last release (1.8.1). When <br>
starting, the RabbitMQ server will detect the existence of an old <br>
database and will move it to a backup location, before creating a <br>
fresh, empty database, and will log a warning. If your RabbitMQ <br>
installation contains important data then we recommend you contact <br>
support@... for assistance with the upgrade.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are considering deploying a HA RabbitMQ
cluster with
Pacemaker and DRBD. HA is very important for us.<o:p></o:p></p>
<p class="MsoNormal">If there is a database schema change in the
future,
specifically what is the process for the upgrade and how does it affect
HA
during the upgrade?<o:p></o:p></p>
<p class="MsoNormal">Also during the upgrade, how do we maintain
durable
exchanges and queues?<o:p></o:p></p>
