You can't swap between different controller chips, the code used to specify the stripe blocks won't be the same. What you can do, is swap between identical controller chips. You have a HPT372 controller chip which is found in the RocketRAID133 like you say. All you have to do is get a PCI RocketRAID133 card and plug your drives into that. You shouldn't need to recreate the array, the card should detect the array information that's already on the disks.
