Can anyone enlighten me as to the process for upgrading a production v1.6 to v.20? Normally I would use the yum update process as described in elastix without tears, this process does not seem to do version upgrades, only updates within a version. Wo what should I do? I can't use the Distro ISO to upgrade as I can't physically put it in the drive of the server as I am using a hosted VPS for the elastix 'box'. Any pointers please?
