I've upgraded my BES to 4.1.6MR1 and Domino 7.0.3MR1.
I have 4.5 software on a handful of BBs, belonging mainly to IT folks for testing. HTML/rich-content/inline images enabled on BES. So far not too much additional load on BES.
I have just read this doc http://na.blackberry.com/eng/deliver..._text_BESD.pdf
and was wondering whether anyone else had experienced any memory issues with a 32 bit BES? Did you upgrade to 64 bit, or are you already running 64 bit Domino/BES?
I'm just trying to get a measure of what other Domino BES Admins do, before I roll out 4.5 handheld OS...
