Will I lose text messages switching from prepaid to postpaid?

[road-hazard]

I'm currently on a prepaid plan. I'm going to be moving back to postpaid. Will (should) my text messages all move over? When I moved from postpaid to prepaid, they automatically moved over and I didn't lose anything. Will the same hold true moving back?

Keeping those text messages is vital. If you do not erase the device, the text messages should stay right where they are.
