Upgrade to Jessie
Debian upgrades must be performed one version change at a time. If you don't know which version you are on, or which version is next, you can find information on the entire upgrade path here.
This upgrade should only be performed if you are already running Wheezy (7).
Upgrade Debian Wheezy to Jessie
- Make sure your existing CanIt installation is up-to-date:
- Now upgrade the OS to Jessie:
- upgrade-canit-appliance jessie
- We have had troubles with some appliances failing to install the Grub bootloader after the Jessie upgrade, so be sure to generate it again for all hard drives:
- dpkg-reconfigure grub-pc
- Reboot the machine.
- tail -f /var/log/mail-daily/current.log or wherever they are to see if working
NOTE: The above commands are for a single machine. If you are upgrading a cluster, then you should modify the steps as follows, starting with the DataBase machine:
- Stop CanIt on all cluster members before each command:
- /etc/init.d/canit-system stop-gracefully
- After the command in step (4) above, run:
- /etc/init.d/canit-system start
- Also, all commands should be run in parallel. That is, run (i) and then (1) on all machines, then (i) and (2) on all machines, and so on, finishing with (ii).
Upgrade to Stretch
With the release of Stretch in June 2017, Jessie is now the Old-Stable version of Debian, however it is still considered to be the stable version for use with CanIt.
While Stretch has been tested successfully and packages are available for it, we still consider it to be experimental. A wiki has been created detailing this upgrade here.
Jessie will still be supported by Debian and CanIt packages will be released for it for the foreseeable future, so you are under no immediate obligation to upgrade. Also, when Stretch does become stable be aware that the upgrade to Jessie MUST be done before you can upgrade to it!
We will send an announcement out when Stretch is determined to be stable. If you are not signed up for our mailing list, you can find it here.
