Upgrade from ActiveMQ 5.4.2 to ActiveMQ 5.5.0 with non-empty KahaDB

Good Day!

We have problem with issue AMQ-2736(https://issues.apache.org/jira/browse/AMQ-2736) on remote sites and wants to upgrade to 5.5.0 version, wich resolved this problem. But network connection with remote sites not stable and we will have non-empty KahaDB at some of them. Does 5.5.0 vesri开发者_运维问答on works with database created by 5.4.2 version and we can simply upgrade software or we must empty all queues before upgrade?

I do not know this from first hand experience, but a colleague has successfully used ActiveMQ 5.5 against a KahaDB created from a previous version. If you really want to try it out, just take a file system copy of the entire dataDirectory from version 5.4.2, and point your 5.5 installation to that copy within your activemq.xml configuration.

I tried latest Fuse Message Broker maintenance release for ActiveMQ 5.4.2 - apache-activemq-5.4.2-fuse-02-00 - and it works good - all "trash" files are removed and we have not detected any message lost or corruption
