Jenkins 2.0 Upgrade

[Sverre Moe]

How can I be sure before upgrade to Jenkins 2.0 that all my installed plugins are still compatible?

Has there been any changes to the API that would require me to update my groovy scripts?

We do not expect plugins to be incompatible with 2.0, except possibly those modifying core UI beyond the supported extension points due to some changes to the UI. But those plugins should be changed to not do that anyway, as we may change parts of the UI in any version for pretty much any reason.

However, we upgraded the bundled Groovy from 1.8.9 to 2.4.x. That could pose a problem, depending on what you or your plugins are doing.

FWIW I haven't seen reports of things breaking so far, with the exception of Linux systems that had enabled AJP (it used to be enabled by default in the RPMs), resulting in an error on startup that can easily be fixed by disabling it.

As always, if you need Jenkins to work and downtimes to be minimal, take a full backup before upgrading that allows you to downgrade, and/or try the new version in a staging environment first.
