Upgrading
|
|
=========
|
|
|
|
Care must be taken when upgrading a server that contains persisted
|
|
messages. The persister log format has changed between RabbitMQ-1.2.0
|
|
and this release. When RabbitMQ-1.3.0 first starts following an
|
|
upgrade it will move the existing persister log to a backup file -
|
|
check the log files for details. Thus the previously persisted
|
|
messages are not lost, but neither are they replayed. Therefore it is
|
|
recommended that the upgrade is performed only when there are no
|
|
important persistent messages remaining.
|
