If data is copied from one san to another san and the lun ids are presented to the host with exactly the same lun ids will the databases have to be rebuilt if they are all on ASM filesystems? The only thing that will change on the machine is the storage.

Host/LUN will change which will change how the linux system sees this allocation.
You would need to update the raw entry to reflect the new storage as the old raw device.
The other issue is what is the status of the node when this copy is made.
i.e. are you copying the data when the database is down so no changes are made while the copy is performed?
