AFAIK dungog packages are no longer supported by the original author (or anybody for that matter).
I believe some code was given to contribs.org when dungog stopped support, but most of the commercial dungog packages with proprietary code are no longer available or supported.
There is an easy way to find out if dungog-rsync works on sme9, & that is to try it out.
If it does not work, then you can lodge a bug report & see if one of the devs is interested to support that package.
You can install Virtual Box (etc) & then install sme9 & test that package using a VM setup, prior to performing any upgrade.
