Upgrade procedure from Davra 5.1
Prerequisites for upgrade
- Valid upgrade base: The only valid upgrade base for Davra 6 in the 5.X series is version 5.1 -- if your version is 5.0.Y, then you will have to upgrade to 5.1 first. A step by step guide on how to do this can be found here.
- Two machines running two Davra installs: You will have to have two machines, one running Davra 5.1 on CentOS 6, and another running Davra 6 on CoreOS, installed using the procedure described in the previous section.
- Root access to Davra 5.1 machine: The upgrade script, which is run on the new CoreOS Davra 6 machine, needs to login, as root, to the CentOS Davra 5.1 server to migrate the data. The script will prompt you for the root user password of the 5.1 machine so be sure to have it to hand.
For the OVA versions of Davra then you need to :
- login to the 5.1 machine as rubanAdmin
- reset the root password: sudo passwd root
Upgrade procedure
- Install Davra 6 on CoreOS using the procedure described in the previous section
- Get a root terminal using
sudo bash - Run the upgrade script using
bash Davra/upgrade-ruban-51-to-6.sh [IP address of the machine running Davra 5.1] > upgrade-ruban-51-to-6.log 2>&1 - Take down your old Davra instance
- We recommend that you change the IP of your new Davra 6 to that of your old Davra server so that your edge devices don't have to be reconfigured for continued data supply.
That's it, you're done!
