Using same .config on different machines

[Arun M Kumar]

Is it OK to use same .config file on different machines.
I had a Dell Optiplex running OpenSuSE 11.3, KV: 2.6.32 for development 
purpose during my college days,
can i use the same config file now on KV: 3.9.10

The command
$ make -j 8
completed sucessfully but

#make modules_install

gives the following error

-------------------------------------------------------------
ln: target ‘Drivers/source’ is not a directory
make: *** [_modinst_] Error 1
