Hi gadado2, I am the author of the DASH Masternode Zeus and yes, it is the easist way to upgrade your masternode.  It has two options for this, one to upgrade the dashd and the option to update the Sentinel, current version is 1.6.0.  You are right, it does not seem to impact payments by not having a working Sentinel, but I am not 100% sure of this.  If you notice you get a POSE Score, please also update the Sentinel, easy as pie using the DMZ.  Also, thanks for your kind words.  I will be making an update to it to handle DASH Evolution (Platform), although Strophy's DASHMate, is pretty awesome too!
