Depends on the way you configure things, but on my mailservers, there are a bunch of config files other than the ones which are @sample'd in the packages, so the sysmerge commands are of limited use. Typically when I've done this, I install the same set of packages, then scp /etc from the origin machine to /tmp/etc, and go through manually with diff and decide whether to copy or manually merge the various files. Same as if I am building on a new machine without changing arch. One thing to be aware of is that binary data files may have a different format depending on the arch. Less likely to be a problem with amd64 / aarch64, but that's definitely happened with i386 / amd64. -- Please keep replies on the mailing list.
