What make & model of awning is it? However, generally the answer is No, you have to replace it. The awning arms are completely different, and the roller tube is at least somewhat different (where the motor gearing connects).
You might find a used awnings at an RV salvage yard, but if you have to pay somebody to install it anyway, you may as well get a new one. You might save money buying the awning yourself, though. Plenty of online RV parts sources.
