车讯:新款杰德/思铂睿混动版或2017年1月上市
The goal of this page is to identify the outstanding issues that must be addressed by Artemis in order to achieve feature parity with ActiveMQ Classic. This page does not list the features which Artemis has beyond what currently exists in Classic.
Features/Scenarios
This section should be used to compare what features from ActiveMQ Classic have been implemented in Artemis. Feature items can be listed, with links to JIRA tickets for longer conversation and hashing out specific feature details. This will help us to more clearly track everything that Artemis needs. This list of features was taken from the Classic features page.
Keep in mind that not every feature must have a ?. Artemis is not meant to be a 100% complete reimplementation of ActiveMQ Classic. Features should only be reimplemented where it makes good sense.

Migration
This section should help to answer the end user question, ‘How do I migrate from Classic to Artemis?’. This should include the identification of any tools that can help make this easier, as well as documenting information and procedures specific to migrating.
- Migration Guide
- Export messages from KahaDB using this tool. The exported XML can be imported via the
./artemis data impcommand. - For non-standard backends (where direct export isn’t an option) follow this example to migrate messages from Classic to Artemis over the wire.
