Hi I have an issue upgrading 1 server from 1.9 to 2.0 . the other servers updated fine without issue .the last server keeps failing so i have a couple of questions . I have all vm's backed up prior to the upgrade so is it possible to uprgrade the os via dist-upgrade and re-run the upgrade script ? alternatively can i copy the 1.9 backups to a 2.0 setup and restore them .thanks for any help that can be provided .
