Upgrading from old version (13.0-RELEASE-p4)

Hi everyone,

I have a couple of servers (amd64) that have been turned off for
quite a while that I now need to reactivate. They are still running
13.0-RELEASE-p4, and when I try to update, I get "No mirrors
remaining, giving up".

Is there any way to upgrade without having to do a full reinstall?
