Exactly. If the tires you're keeping are old enough that you worry they'll blow out, then replace all four. Otherwise. The tires with the most grip always go in the rear. It's better to have a car prone to understeer than oversteer, which having more grip in the rear induces.
This is safer in all low-traction conditions. Why? Because it's better to not be able to move than to spin out of control with a car prone to unpredictable oversteer.
If the old tires aren't that bad (>6/32), then it might be a moot point - do whatever you want. If they're 32, I'd definitely want them in the front or replaced.
