Thanks for the link , I follow the instruction in https://www.digitalocean.com/community/questions/how-to-unofficially-upgrade-to-fedora-21
After do it, i had some problems
i could not restart , or shutdown the server, when i tried to reboot the server i got this message
“Failed to start reboot.target: Activation of org.freedesktop.systemd1 timed out Failed to open /dev/initctl: No such device or address Failed to talk to init daemon”
and when i tried to start any service i got the next message “Failed to start fail2ban.service: Activation of org.freedesktop.systemd1 timed out” (this example is with fail2ban service in each service the name of the service change)
or when i tried to see the status i got … “Failed to get properties: Activation of org.freedesktop.systemd1 timed out”
I had to choose another kernel “Fedora 21 x64 vmlinuz-3.17.8-300.fc21.x86_64” , applied all the updates , i restarted the server from the web panel
and installed again fail2ban because the module relate with Firewalld was erased with the updates
and now all is working ok.
Thanks
At the moment all I can think of is this
Don’t know of any official way to do it but could be wrong

I haven’t tried it yet, as I wanted to make a snapshot of my Droplet before proceeding, but my understanding is that the Fedora project makes available a script called ‘fedora-upgrade’ that you can install using yum and then run. Has anyone here tried that yet?
