        Hi,
that's not that easy, as you'd need to find related patches in the
evolution-data-server and libsoup, which can go down to NSS/NSPR
library and eventually glib-networking or gnutls, whatever your ancient
libsoup might be using. It would be also "a huge waste of time" to try
to find the right patches in the respective libraries.

It's possible to compile necessary bits in a different prefix, but the
gap between 2.28 and 3.20.x is too huge, with too many changes (like
the switch from gtk2 to gtk3), that it would just garble your system.
And with the evolution-data-server being a core part of the GNOME
environment you'd end up in a dependency hell quite easily, both in
compile time and also in the run time.

The system update looks like a good idea, though the latest versions
work "slightly" differently than that your (GNOME itself significantly
differently for sure).
