THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
- In the first rolling bounce, we replace the byte code (i.e. swap the jars), set the config
upgrade.from="older version"
(possible values are "0.10.0" - "3.34"), and then bounce each instance to upgrade it.
Theupgrade.from="older version"
config will ensure we are still writing out only the old serialization format until all instances are on the new byte code, at which point we can be sure that all instances in the group will be able to successfully deserialize the new format if we were to start writing it. - The second rolling bounce is to simply remove the
upgrade.from="older version"
config and bounce each instance for it to begin writing in the new serialization format.
