Appendix D Backdating Your System

This appendix contains instructions for returning your system software to a previous release (backdating).This chapter describes general backdating methods that will work in most cases.




	WARNING! If you are on an N-Class or A-Class system you cannot backdate to software before 7.0.




	CAUTION: Perform a backdate when you have updated your operating system version and have serious problems. Only do this under direction from your HP representative or Response Center.

Do not use the directions in this appendix to backout patches.

If you applied patches using staging areas, refer to Appendix G “HP Stage/iX Reference” for directions on backing out of a staging area.
If you applied patches separately from a system software update, refer to the HP Response Center, if you have a software support contract, or your HP representative for directions on backing out patches.
If you applied patches as part of a system software update, follow the procedures in this appendix. The patches will be removed as part of the backdating process.

This appendix is divided into the following sections:
