Upgrade ejabberd in NS6 to latest version


during the last month the android app Conversations became more and more interesting for me and my friends in our soaring club.

On our Clubserver Ejabberd is running on NS 6.8 but some new features of Ejabberd, which are very usefull and comfortable are only available in the actual version of ejabberd.

So the question is: is it possible to upgrade ejabberd from ejabberd-2.1.13 to 16.12 ???

Is there anybody who tried it yet ?

NethServer Version: 6.8
Module: Chatserver

with best regards from Leipzig
