I'm planning to bump two amd64 virtual servers from 5.2 to 6.1.5 or 7
tonight.
In the past, I've over-written the kernel with the new version,
rebooted, then untar'ed the OS tarballs, over-writing everything, then
run postinstall to tidy up /etc, and it's "just worked" - everything
in pkgsrc kept working (cyrus, sendmail) and my home-made compiled
stuff did too (mostly older Plone instances)
Any issues I might have doing that going from 5.2 to 6.1.5? Or, is it
safe to jump straight to 7 doing that?
I have updated 5->6, and have not tried 6->7. But surely others have.
I use pkgsrc/sysutils/etcmanage which has scripts to automate what you
describe, as well as merge /etc files.
Note that with an upgrade, pkgsrc and so on will work, but once you
start building some things, you may need to build/install everything
because some libraries will change major version.
