Hi all,
The upgrade path from Zentyal Server Development 7.1 to 8.0 has been published now. When you upgrade the 'zentyal-core' package to its latest version, "Upgrade button" will appear on the Dashboard.
We would recommend you to follow this checklist to avoid issues:
* Make sure you don't have pending updates
* Back up your server and data before upgrading
* Make sure that there are no errors in the /var/log/zentyal/zentyal.log file
* Make sure that there is space available on the disk
* Make sure that the server is updated
* Make sure that there are no broken packages
* Make sure that there are no errors in the internal Samba database or in the MySQL databases
* Make sure that you have Internet connectivity
* Click on the Upgrade button on the Dashboard
* Make sure that the packages have been updated
The official documentation for Zentyal Server 8.0 will include more detailed instructions.
Looking forward to receiving your feedback and comments.
