RE: Upgrading Kolab 3.4 to 16
NOTE: The folowing has been tested on a throwaway VM I'm using to test upgrades. There's no guarantee that something won't break. Do it at your own risk.
Download the package:
Untar and copy the relevant bits:
tar -xf 3.0.5.tar.gz cp -R sabre-http-3.0.5/lib/* /usr/share/php/Sabre/HTTP/
No restart should be required.
