netbackup win 2003 to win 2008 client restore

Hi ALL,

I am performing a client server restore from win 2003 to win 2008.

I am using this link : 

http://www.symantec.com/business/support/index?pag...

1...Can i do a complete client  restore on a  win 2008 client from a win 2003/NT/XP  CLIENT backup(system state restore as well).any forward/backup rules for OS while restoring?

2...Hardware changes in this link means?

3....Restore to a different client means here?  (if my original client is win23 and i am restoring on win12.is it?).both OS needs to be same or can be different?

4...can NBU perform complete server restore to the SAME os client??
