3-way restore to address migration from one nas to another?

We are changing filer providers but we need a way to be able to access backups made on our "old" filer.

The original backups were to tape

Is it possible to run the old filer simulator (VM) and do 3-way ndmp to it via the new filer? Ie tapes attached to new filer, reads the data and sends it to the VM

Thanks in advance Jim
