Hi folks, I have lenny running on a headless virtual server being hosted by a small hosting provider and now I'd like to upgrade to squeeze. The box does not serve any commercial purpose, but it does handle a portion of my private email traffic. So I'd like the system not being down for more than 12 hours.
In case of any service failures after doing 'sudo aptitude safe- upgrade' I'd like to know some methods to smoothly revert to my current installation. Best would probably be to ask my hosting provider to make a disk snapshot / disk image, but I'd like to know if there are other possibilities. What's your experience? Did you try out something of these: - Using undo mechanism of aptitude (how does this work?) - using 'dpkg-get-selections >currentstate.txt' and 'dpkg-set- selections <currentstate.txt - making a tar backup and restore it afterwards while the system is running, then reboot? - making small incremental upgrades of individual packages with aptitude instead of upgrading all packages at once / test the new service / revert to old version if necessary (The latter is the way how i've done it with the previous 2 debian releases) What's your recommendation / experience for downgrade?
