system restoring after disaster

Hello
I use Veritas Backup exec 10d. I conmsider situation when my servers
will be totaly destroyed.
I know that I able to recover system and all data with  IDR whan new
server will be exacly like old one. But can I use IDR to restore
system/data using different server I mean with different  configuraton
from different  producer ?

Thanks in advance
