Well, that was quick… exactly one month ago I upgraded my server with the latest patches and I’ve done it again, but with a newer patch. I just updated and tested my server and it passed the tests with flying colours. I anticipated no issues from reading the knowledgebase article on what was solved and changed.

So this means that you can upgrade your Mac mini safely without any problem if you used my instructions for the installation of the mail and web server. I can’t vouch for any other software you might be using.
