I upgraded the system from CU8 to Cu10
I have read somewhere if you are upgrading from R3 RTM your version will end in 111, if you ugrading from any cumulative update it will be 110. If that was the case which is ok to have different version
(There is another problem which my client (win 7) application version (6.3.3000.111) not able to connect. Its giving the common error "The server is unavailable. Check your configuration and network connection and try again"
Please suggest due to this my client giving this error or it could be some other reason.
