Did the new charts make it into 10.3? Not gonna bother with an upgrade if not.
Yes, sir. Download and install. Functionally, the NPM infrastructure is updated with each release. Primary installations and extensions thereof must be on the same version to ensure that NPM 'works'.
HTH,

Does 10.3 need to be installed on additional Web Consoles?
Yes, if you have upgraded your primary NPM installation, you will need to upgrade any and all Additional Web Servers and Additional Polling Engines you have installed.
So I have to download that huge Additional Web Console package again?
