Talking about migrations

After my last post I thought I might as well point out some other resources that come in helpfull when migrating to a new z/OS version. So I'm not limiting this to just z/OS 1.9 as some of us are still migrating to z/OS 1.7. They're in no particular order :

-> The Migration checker from z/OS Download page

See post below

-> z/OS migration manuals
Here you find the most important general manuals for the last four releases (1.9, 1.8, 1.7 and 1.6). You get a manual per z/OS that you can migrate from. E.g. for z/OS 1.8 that's from 1.7, 1.6 and 1.5. For z/OS 1.9 that's from 1.8 and 1.7. Remember : coexistence has come down from N-3 to N-2.

-> Migration and installation Resources per release
Here you find separate pages for the last three releases. There are some additonal manuals like 'Planning for Installation', 'Program Directory' and 'ServerPac Using the Installation Dialog'.

z/OS V1R9.0 migration and installation
z/OS V1R8.0 migration and installation
z/OS V1R7.0 migration and installation

Which is also nice : there's on each of these pages (near the top) a link to an installation planning wizard. Here's a link to the one for z/OS 1.9. What's it good for : it's an interactive version of the 'Planning for Installation Guide'. "Installing z/OS using ServerPac or CBPDO? The z/OS V1R9.0 Installation Planning Wizard can guide you through all the z/OS installation planning tasks".

-> z/OS Integration Test Web site
I like this System z Platform Test site. I'll let them describe themselves what they are actually doing :

We are a team of z/OS testers and system programmers who run a Parallel Sysplex on which we perform the final verification of a z/OS release before it becomes generally available to customers. As we do our testing, we gather our experiences, hints, tips, and recommendations and we publish them as the System z Platform Test Report for z/OS, formerly known as the z/OS Parallel Sysplex Test Report. Our test reports can be found in Our Test Report Library.

No publications on z/OS 1.9 yet. The last one e.g. is 'System z Platform Test Report for z/OS and Linux Virtual Servers'. To give you an idea : it decribes their sysplex environment, their networking environment, their security environment, using the zIIP, Using IBM Websphere Application Server for z/OS, Migrating to DB2 9 all in a very practical manner. The appendices give you e.g. some of the Parmlib members, some RMF reports . . . Here's the table of contents.

-> Redbooks
These redbooks give a description of all the new functions in a release, why they were improved and what the implications are. There are many examples on how to implement them. One example : for z/OS 1.8 WLM enhancements are described and one of them is 'Improved management for zAAP Workloads'. One of the zAAP related subjects is 'Improved IFAHONORPRIORTY=YES processing' : how was it before z/OS 1.8, what's changed and how do I handle the new parameters ?

So, we're eagerly waiting for the 'z/OS Version 1 Release 9 implementation' redbook !

z/OS Version 1 Release 7 Implementation
z/OS Version 1 Release 8 Implementation

Of course there are a lot more resources than just these.
If I've missed some crucial ones, just drop a comment !
