Chapter 1Migration Strategy, Plans, and IssuesThis chapter describes strategies for migrating a ChangeMan ZMF instance to version8.1.3. It presents a model migration plan that you can use as a template for yourmigration plan, and it presents sample scripts you can use as templates for your ownconversion-day script.The relevant chapter for your migration each have a table of contents for your migrationcan also be used as a high level checklist (They are listed as steps).Migration GuideAssumptions12Migration Strategy12Model Migration Plan15Sample Conversion-Day Script1711
Chapter 1 Migration Strategy, Plans, and IssuesAssumptionsThe following assumptions are implicit in this migration guide: You have read "Choosing the Right Installation/Upgrade Manual" on page 10 to verifythat this migration guide is the correct manual for your instance of ChangeMan ZMF.Before you begin planning your migration, you have read the entire ChangeMan ZMFInstallation Guide and this current migration guide.You can build multiple ChangeMan ZMF test environments that model key features ofyour current production ZMF architecture and customization.You manage ChangeMan ZMF custom components with a ChangeMan ZMF instance.Custom components include skeletons, panels, exit programs, started procedures,housekeeping JCL, and so on. The release level of the ZMF instance you use tomanage custom components is not important.Migration StrategyThis section: Lists factors that limit how you can migrate to ChangeMan ZMF 8.1.3. Outlines measures you can take to reduce risk in your migration to the new version. Discusses the advantages of release libraries. Outlines a strategy you can use to convert P (production) instances before youmigrate your ChangeMan ZMF D (development) or DP (development-production)instance.ConstraintsAll package and component functions begun under pre-8.1.3 ChangeMan ZMF releasescan be continued under version 8.1.3, including promotion/demotion and install/backout.However, there are constraints on the migration to ChangeMan ZMF 8.1.3: There is no process to deconvert from ChangeMan ZMF 8.1.3 back to a pre-8.1.3instance. Because of the changes to the structure of ChangeMan ZMF files, there is noprocess to deconvert data stores that are processed through conversion programsthat prepare them for version 8.1.3. Installation jobs that are file tailored under ChangeMan ZMF 8.1.3 will not runsuccessfully under pre-8.1.3 versions. Only one type of phased migration to version 8.1.3 is supported: Convert P instancesto version 8.1.3 before you convert D and DP instances.You cannot convert DP instances before P instances because installation jobs that arefile tailored under ChangeMan ZMF 8.1.3 will not run successfully under pre-8.1.3versions.12Serena ChangeMan ZMF
Migration Strategy If you back out a conversion to ChangeMan ZMF 8.1.3, you must restore all convertedZMF master files to their pre-conversion state. If you back out the conversion afterdevelopers have performed work under ZMF 8.1.3, you will have these problems: There will be no record of the changes that developers made to componentsbetween the conversion and the conversion backout. Such changes remain instaging libraries, but these changes are unknown to ChangeMan ZMF, so they willcause audit errors. Staging versions recorded between conversion and conversion backout are lost. Packages and staging libraries that were created between conversion andconversion backout are unknown to ChangeMan ZMF. However, staging librariescreated during that time will remain on DASD and in the catalog, and they willinterfere with the allocation of staging libraries as developers try to recreatepackages that they created under 8.1.3. Installation jobs that are file tailored between conversion and conversion backoutwill not run.Installation JCL IssuesInstallation jobs that are file tailored on a pre-8.1.3 instance can run on a version 8.1.3instance. When ChangeMan ZMF 8.1.3 installation programs process an installationPackage data set created under a pre-8.1.3 version, the Package records are converted toversion 8.1.3 before they are inserted into the ZMF 8.1.3 Package Master.The challenge is that the installation JCL created on a pre-8.1.3 ChangeMan ZMF instancemust execute with version 8.1.3 libraries to install on a version 8.1.3 instance.Customers may have devised a solution to this issue when they upgraded ChangeManZMF to their current release. Here are two solutions, one solution for customers with asimple ZMF environment, and one solution for customers with a more complexenvironment: If all of your ChangeMan ZMF instances use the same production load library, you canconvert all ZMF instances at the same time, replacing pre-8.1.3 components in theLOAD library with version 8.1.3 components.If you have a complex environment and use release libraries (libraries with a uniqueDSN for each ChangeMan ZMF release), you can use INCLUDE groups for JOBLIB andSTEPLIB statements in installation skeletons. By changing the libraries in theINCLUDE group stored in a PROCLIB, you effectively change the JOBLIB libraries inthe installation jobs at run time.Strategies to Reduce RiskUse these strategies to reduce risk in the process of migrating a pre-8.1.3 ChangeManZMF instance to version 8.1.3. Migration GuideSegregate delivered vendor versions of components from custom components; storethem in separate libraries. Preserve the vendor version of all ChangeMan ZMF 8.1.3components so you can revert to the original versions if your modifications do notwork as expected.Create new physical libraries for ChangeMan ZMF 8.1.3 custom and vendorcomponents. Do not update libraries containing pre-8.1.3 components with version13
Chapter 1 Migration Strategy, Plans, and Issues8.1.3 components. Not all pre-8.1.3 components are brought forward into version8.1.3. Analyze the ChangeMan ZMF 8.1.3 components that you can customize, andcustomize these components as appropriate for your installation and your ChangeManZMF version 8.1.3 instance.Use the ChangeMan ZMF M R Option to locate and analyze modifications you made topre-8.1.3 components. If you do this, keep in mind that customizations you made tocomponents for an earlier ZMF release may no longer apply to components in the newZMF release distribution libraries. The M R Option is included in ChangeMan ZMFdistribution libraries. Any version of the M R Option is suitable for this task. If you donot already license the M R Option, contact your Serena account representative.Preserve ISPF statistics on vendor versions of ChangeMan ZMF components. SerenaSupport may need the USER and the CHANGED date from the delivered version of acomponent to help you diagnose problems.Create two sets of change packages for your customized ChangeMan ZMF 8.1.3components: Packages with components that are installed into ChangeMan ZMF 8.1.3 libraries inproduction, such as exit programs, ISPF messages, panels, and skeletons. Packages with components that are installed into system libraries in production,such as JCL, cataloged procedures, and CLISTs.ChangeMan ZMF 8.1.3 libraries can be populated before the actual conversion. Unlessyou make the name of your started procedures and log-on CLISTS version specific,you cannot update system libraries until the day a pre-8.1.3 instance is converted toversion 8.1.3. Test all data conversions in the migration process with copies of your pre-8.1.3production data to determine how much DASD is required for intermediate and finalfiles and to determine how long each process will run on conversion day.Create a conversion plan, write a test plan, and build a detailed script for the day ofconversion. Build a script for reversing the upgrade in case there are serious problemsafter conversion that cannot be fixed.Execute a dry-run conversion before you execute the actual conversion. If you haveproblems, correct the problems and execute the dry-run conversion again until it runssmoothly.Ensure that your conversion scripts contain file backups that create a pre-conversionsnapshot that you can reload if you must back out the upgrade of a ChangeMan ZMFinstance. Also verify that your backups can be restored from. Ensure that yourconversion scripts contain post-conversion backups that create a snapshot that isincluded in your standard disaster recovery backups.Kepp all job logs in their entirety from your final conversion activites.Libraries By ReleaseThere are significant benefits to creating a new set of uniquely named vendor and customproduction libraries for each release of ChangeMan ZMF. Unique production libraries allow: 14Phased migration where there are multiple ChangeMan ZMF instances. Two ZMFreleases can coexist in the production environment.Serena ChangeMan ZMF
Model Migration Plan A simpler conversion-day process, because most components in the new release canbe installed into production before conversion without interfering with the old release.When you manage custom ChangeMan ZMF components with a ChangeMan ZMF instance,implement unique production libraries for a release by creating a new application for eachnew ZMF release.Strategies for Sites With Multiple ChangeMan ZMFInstancesIf you have many ChangeMan ZMF instances, you may not be able to upgrade all of thoseinstances to version 8.1.3 at the same time. If you have uniquely named vendor andcustom production libraries for each release of ZMF, you may be able to convert instancesindividually or in groups: You can convert A (ALL) instances one at a time or in groups.You can convert P instances before you convert the D or DP instances thatcommunicate with them.You can convert a D or DP instance and all of the P instances it communicates with.You cannot co
