Upgrade questions about Prime Infrastructure 1.1.1.24 to 1.3

Question

               My existing NCS is installed with the small deployment and I'll have a total of 94 AP's but we are installing a new data center and replacing the existing 2 WISM blades for 2 new 5508 WLCs and added 20 more AP'S which will total 114 AP's and 4 controllers. The old WISMs blades and new 5508s will be up together until we migrate exisitng AP's to the new 5508s, so do I need to install the medium deployment since Table for Scaling Prime Infrastructure states:
Medium: 500 Total. The mix of devices may included up to:
     Wired devices: 300
     Controllers: 5
     Autonomous AP's: 300
     Unified AP's: 300
Small Deployments are for a total of 250 devices "with up to" 100 Unified AP's and 2 controllers?? 
Also as part of the download of software for PI 1.3 it   includes Automated Deployment Gateway is this a required piece to install for PI??  We don't use Cisco works so I'm not installing the LMS piece. 
thank you,
Sandra

Answer 1

Isn't it rediculous the message says:::
Error(s): You must correct the following error(s) before proceeding:
Error:Unknown Exception Occurred. If the problem persists send logs to Tech Support.
And the fix is to use a different browser?
BTW:: Good Idea to try a different browser.  By the looks of the Error Msg, it just didn't look like a browser issue to me so I didn't think to do that but certainly will next time on this and probably many, many, many other issues I see-
We only spent about an hour chasing our tails around to see what the issue was.
Again good catch!
I was speaking w/ another customer today who mentioned if the application were re-written to use HTML 5 these type problems would go away.
Oh well.
Glad I could help you get all the way upgraded and all the way up and running and able to push templates to your lightweight APs.
