I need to install an additional application server for our BW abap and BW-java system on the same host.
Presently we have 2 application server for each system.The OS is windows and DB is MYSQL.
Now the situation is the 2 app servers are installed in 2008 R2 and the new one is in 2012.
So can we go ahead and install the application server or the versions should be same?
