Important Notes

Upgrading

It will be possible to easily upgrade from a existing Zentyal 2.2 installation to Zentyal 3.0. However you'll have to wait some weeks until we publish the migration tool for this purpose. Moreover, due to the new base distribution and other mayor changes we can not guarantee that everything will be migrated straightforwardly: a list of known issues and services that will need reconfiguration will be published together with the migration tool.
For those who are already using Zentyal 2.3, you just need to edit the /etc/apt/sources.list file, replace the 2.3 repository with the 3.0 repositories and upgrade all the packages with: sudo apt-get update && sudo apt-get dist-upgrade
