Using same .config on different machines

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
-------------------------------------------------------------

As long as the .config includes all the moduled needed for all the machines in question. That's basically what a distro kernel does - include all the drivers for all supported hardware, and that's why a distro will usually boot on damn near anything.

You really want to do a 'make oldconfig' to update it for all the config variables that got added/changed between .32 and 3.9.

That looks suspiciously like in fact the build did *not* complete successfully.

If you do a *second* 'make' - does it attempt to rebuild anything? Often an error message will scroll away un-noticed.;

And I'm not sure where it got 'Drivers/source' from, that sounds like a busted
build or install environment. You didn't have any M= or O= variables that you didn't tell us about, did you?
