Hi, Im getting a downtime of 4 hrs to do porting of bootdisks.
Currently, the system is running on Sf4800. 2 internal disk 36G connected to a SE3510 storage.
We're getting 72G disks and we want to restore the OS from the current 36G to the 72G disk. System is under veritas volume manager ctrl. Any steps provided would help. Thanks.

config as follows:
