Migrating from OpenNebula 2.x

There has been a bump in the major version number of OpenNebula. There are three main areas that need attention when upgrading your installation (if you are an OpenNebula 2.x user):

Database, The DB schema has re-design from scratch, to ease the transition you should use the onedb tool to automatically upgrade your system.
User Interface, There are minor changes in the CLI and user interface. The most notably ones are that now you can reuse names, and that images and networks can not be referenced by name, use NETWORK_ID and IMAGE_ID instead.
API, New methods have been included for the new features. Also there are a few changes in the current xml-rpc methods.

For a complete set of changes to migrate from a 2.x installation please refer to the new Compatibility Guide. You should also read this document if you are an OpenNebula 2.x user.
