Greetings, A friend of mine is running 3.3 He asked what I thought about going to 4.4 I imagine it is best to backup and fresh install and migrate old configs and data What is the wisdom on the list I remember going from beta 3 to 3 a long time ago. Anyone ever upgrade from 3.x to 4.x without problem and how so? I didn't see a lot on the www other than some apt-get info Thanks in advance - rh -- Robert - Abba Communications Computer & Internet Services (509) 624-7159 - www.abbacomm.net

I think I recall from previous similar threads that people *have* upgraded from 3 to 4 but the general concensus was that if you can, you should rebuild from scratch. The main benefit being any configuration gotchas will be apparent straight away as you're configuring each specific aspect of your/their system. Will.

Upgrades across major kernel and glibc versions are at best very difficult with yum/apt-get. The most likely result of attempts to upgrade across major versions with package management tools is a broken system.> without problemNot really. Expect lots of left-over orphan packages and problems with system and end-user configurations.> and how so?Use "rpm -qa --last" to find packages that pre-date the upgrade and deal with them by removal and/or forced/manual updates. Look for all the *.rpm* files in /etc/... and reconcile differences with current versions of config files. Fix numerous user GUI/application problems. Or [highly recommended], back up config files and user files to accessible media and do a clean install. Use the backup as model/example to configure the new system. Create new user home directories and selectively copy/link stuff as required from the backup. Keeping old GNOME/KDE configurations in place is guaranteed to cause problems. I like to keep the old installation on-line and still bootable and accessible and do a fresh install on a separate hard disk (or at least on separate partitions) and be able to boot back to the previous version as a fall-back.
