1. We strongly recommend evaluating YouTrack 6.5 EAP builds in a test environment!
   Otherwise you can revert to your current YouTrack version only by rolling back to a pre-upgrade backup of your database. Rolling back means that you will loose all the changes made in the EAP version!
2. Please refer to upgrade instructions and distribution-specific procedures before upgrading.

To upgrade to YouTrack 6.5 EAP, regardless of the distribution type you use and assuming you run the EAP build in the test environment, please proceed as follows:

1. Back up your database.
2. Stop your currently running YouTrack.
3. Start the fresh YouTrack EAP build.

If you prefer to try all the fresh goodies without any installation and configuration, simply create a user account in our [YouTrack Harmony InCloud EAP|http://harmony-eap-sandbox.myjetbrains.com/youtrack/registerUserForm] instance. We'll be updating it to the latest build as soon as we can deliver.

{panel:bgColor=#FFFFFF}(!) *What you need to know about this server*
* By default, all currently available features are enabled for _all users_.
* This is Early Access Program, and we reserve the right to update the server as often as we see fit, without any additional announcement, and thus you might encounter a brief periods of downtime. Please be patient.
* We might update the build, which runs on the hosted EAP instance, more often than we publish stand-alone EAP builds (e.g. for testing purposes), and thus the number of build on hosted instance and the number of the latest published stand-alone EAP build might be different.
