Before I hit the GO button, I have had a look at the changelog lists
and I think we should be OK with a straight upgrade, but if anyone has
any other comments on the large version change to be aware of please
feel free to reply! :)
I'm currently at compatibility_level = 2 on 3.3, and will happily
provide details of postconf if needed, but if there are any obvious
gotchas will look at those first.
The suggested post-upgrade ompatibility_level has not changed between
3.3 and 3.5. That's a hint that there are no major barriers to
upgrades. And even if there were some preferred configuration changes,
they'd be guarded by the compatibility_level.
By all means, do read the release notes, but you can expect Postfix to
be backwards-compatible.
