Hello guys.
I have a couple of ancient FreeBSD install that I have to bring into
this century (read either 10.4 or 11.1) :-)
I'm talking about a FreeBSD 8.0-RELEASE-p4 and a couple of FreeBSD
9.3-RELEASE-p53.
I've just done a 9.3 to 10.3 upgrade with freebsd-update and pkg.
Networking wasn't avalable when the system was running 10.3 kernel with
9.3 userland so I did that part of the update on the console.
That system started life as a FreeBSD 5.x system and got left to rot at
that version for a long time because it was an internal system with no
external security exposure. I gradually upgraded it (using source
builds) from major version to major version until I got to 9.3 and then
did the 9.3 to 10.3 as a binary upgrade.
Only other trap I fell into with was packages. The system uses ldap for
auth although fortunately it does have some local network accessible
accounts. ldap auth was broken until I did the package update as the 9.3
pam_ldap modules caused SSH to delay password based authentication and
the auth processes seg-faulted.
What upgrade strategy would you suggest?
Direct jump into the future (8 -> 11)? Progressive steps (8 -> 9 -> 10
-> 11)? Boiling water on the HDs? :-)
If freebsd-update will do an upgrade from 8 to 10 or 8 to 11 and you
have console access it ought to work. The upgrade process can be rolled
back if the system doesn't like the new kernel for some reason and
nothing gets installed anywhere else until the second stage of the
upgrade. I'd probably go via 8->9.3->10/11 as those are the upgrade
paths that were well tested.
Also don't forget the full system backups before starting. :)
