Hi Kat, ok and if i am not mistaken i need to perform the same config for 
all agents right ?

So here is the idea that i feel is perhaps the only solution.
Stop the server, erase the RIDS and then have our customer deploy a script 
in order to stop all the agents and then install the version 2.8.3 and then 
finally erase the RIDS files. Once done restart the server and then restart 
the ossec agents.
