The generally accepted wisdom (which I am repeating because I agree with
it) is that when updating major versions you should:
1. Carefully back up your configuration files and data
2. Do a clean install of the new version
3. Update configuration files
4. Restore data
5. Re-install your ports.
What I usually do for step 3 is to un-tar the old configuration files in
a new directory and then diff -ur old/etc /etc, and after ports are
installed I diff -ur old/usr/local/etc /usr/local/etc.
For step 5, I have a recommended update procedure in the portmaster man
page. Even if you don't intend to use portmaster to re-install your
ports I recommend installing it and reading that part of the man page
before you do your update to get an idea of what is important for you to
restore.
hope this helps,
Doug
