I have the below configuration where my ES2 system is installed. Can this support the ES4 version too.
Application server: Weblogic 10.3.0.0
BEA JRockit(R) build R27.6.0-50_o-100423-1.6.0_05-20080626-2104-linux-ia32
Linux version: 2.6.18-371.8.1.el5 GNU/Linux
Or do i need to update the above things first then do the ES4. Also does anyone have an idea how much time it will take to upgrade the things.
