[OCLUG-Tech] Advise needed regarding Ubuntu upgrade
I have at home a server still running Ubuntu Maverick server. I know
this is very old but it is very stable: It survived a move across the
Pacific and I've had uptime up to 200 days: I only turn it off when we
go on holidays.
I tried in the past to upgrade it to Natty and Oneiric using
"do-release-upgrade" but I got error messages while upgrading and the
system became unstable after the upgrades. I had to go back to Maverick
by restoring from a Clonezilla image I made beforehand.
I know now I am really behind the curve and need to upgrade (mostly to
run zfsonlinux and xen): I would like to run Precise like on my backup
server. This server holds 9TB of data in a RAID6 served using samba and
NFS. The boot drive is a Seagate Momentus XT 500GB and the RAID6 array
is composed of seven 2TB drives formatted using XFS. It is also my main
squid proxy. I can't risk screwing up with this much data because I
can't back it all up.
Would it be possible to install Precise, from a DVD, on top of the
actual Maverick install while preserving the content of /home, /etc and
/var/log? i.e. without using "do-release-upgrade". Can I avoid another
install from scratch?
