Understanding the Changes

Before You Run Pre-Upgrade Tools

Before going on, everyone must read:

This should take you two to six hours, depending on how fast you read and whether or not you already have some knowledge of the topics (from other vendors' systems, or from an HP class, for example).

Before You Upgrade to 10.01

Before upgrading to 10.01 (but not necessarily before doing the pre-upgrade tasks in this chapter) you should also read:

This should take less than three hours to read.

If the 10.01 system will continue to operate with 9.x systems, you should also read the HP-UX 9.x/10.x Interoperability Guide (HP part number 5963-8920). A printed copy of that manual is included in the "Upgrade Tools" package.

	NOTE: If you are going to upgrade an HP-UX ("DUX") cluster, you should also read: The section on "NFS Diskless" in the Release Notes for HP-UX 10.10. The NFS Diskless Concepts and Administration white paper, particularly the section on setting "shared" and "private" policies (you'll find a similar discussion under "Planning Your Cluster Policies" in chapter 11 of the 10.01 version of the HP-UX System Administration Tasks manual) and, for important information on disk space and swap, the "Questions and Answers" near the end of the document (included in slightly abridged form as Appendix B “NFS Diskless Questions and Answers” of this manual).
