Thank for your advice, i already test the upgrading v5.8 to v7 without any error. We can retrive back the old database by summarize data.
the only thing is the web base for ccm is to slow to open. it take about 15 to 20 second to open the ccm web on server side or client side.
We run on server 2008 R2 64Bit with sql 2008 r2. already diasable User Account Controll,disable data execution, install iis and msmq.. but still same, it to slow to open.
CCC can open without any delay time. Do you had face this issue? .
I had install ccm V7 in window 2012 r2 64 bit and is running ok on my other customer side. This problem never happen before, it is first time.
