Use a step file, but if is assembly mates will be lost!

There is no option for this unfortunately. It is simply an inconvenience designed to force users to upgrade to newer versions.

Save it as a Parasolid (x.t.) this will at least give him the full geometry just no history...

use Parasolid (x.t.) or IGES. May be at SW2013 they create such function for saving file. I hope
