Building 7440 from 7420 image

[Redhat]

We are planing to restore make_tape_recovery from RP7420 to RP7440. What are the prerequisite we need to keep in mind before cutting ignite image like
1) Updating Ignite sw at source server
2) updating HWE bundle in source

Is there any other best way to clone the server without big pain?

There is no partition.

[Scot Bean]

Consider the DRD product, it has a clone operation that is easier to use.

Those models are close enough that it should be OK, assuming the patches are failly recent on source machine.

[Redhat]

sorry to mention .The OS version is HPUX 11.11 64 bit. I hope v1 doesn't support DRD.

[Scot Bean]

Correct, DRD is not an option for 11.11.

Another option is to not clone, and just install fresh.

The hardware (rp7420 and rp7440) is the least important part. The most important compatibility issues are with disk interfaces (SCSI or fibre), disk types (especially arrays), and LAN cards. The source system must have the drivers for all the cards installed on the target machine. Remember that the HWE bundle will install the latest version of the installed drivers. It won't install drivers for cards that are not in the old system. And if the target has SAN and/or high end disk arrays that are not in the old system, you'll need to add the new array support tools.

[Redhat]

I have the installed product on the source server.

There would be surely some changes will be there as per the new hardward is concern like the following new cards will be there:

HP Intgr rx7640/rx8640I/O Rmkt Backplane
HP PCIâ X 4 Port 1000Baseâ T GB Rmkt Adptr
HP PCIâ x 1p 4G FC 1000BT Rmkt Adapter
HP rx76/86,rp74/84 146GB 15K Rmkt HD

anyway in old server igelan driver,U320 SCSI driver are there.

comparing the hardware ,what preactivity I should take care for a smooth recovery from make_tape_recovery archive.experienced command is expected.
