PeopleSoft uses the term “Upgrade” in a special sense – an upgrade is the migration of any object or objects from one PeopleSoft Database to another, and the subsequent adjustment of the PeopleSoft system to accommodate the new objects.
When you upgrade to new PeopleSoft Release you are provided with a new database, as well as the information you need to adjust your system components – COBOL statement, SQR’s, the system messages and so on, to work with objects in the new database.
· Application Tables and other definitions like Records, Pages, Menus, so forth.
Application Tables contain the PS_ tables that contain the online Application
A PeopleSoft upgrade requires a lot of planning, time, resources, testing, and development.When upgrading to a new release of PeopleSoft it may be required to upgrade the hardware and software environment; You may have to install new RDMS software, new server machines, upgrade third party tools that make up the complete environment and all of this software should be supported by PeopleSoft. For this you need to consult the Hardware and Software Guide or the Platforms Supported from PeopleSoft Connections.
The PeopleSoft Upgrade process streamlines copying system objects such as records, pages and PeopleCode from one PeopleSoft database to another and finally into your current production database.
When you do upgrade to a new PeopleSoft release, several upgrade passes are required to ensure that whenyou perform the final pass your upgraded production database performs as you expect. You must complete allof these passes to complete your upgrade. The first pass is called the initial pass. In this pass, you create a copyof your production database referred to as Copy of Production. You then take the delivered database (the onewith the new PeopleSoft release delivered with your product) called the Demo database, and incorporate themodified objects into the Copy of Production to create your first upgraded Copy of Production. In this passyour Demo database is your Source and the Copy of Production is the Target.
After you complete the initial pass, you begin the first test Move to Production pass. In this pass you createanother copy of your production database called the New Copy of Production. You take the upgraded Copy ofProduction (the one created in the initial pass) and incorporate the modified objects into the New Copy ofProduction to create your second upgraded Copy of Production. In this pass, the upgraded Copy of Production(from the initial pass) becomes your Source and the New Copy of Production becomes your Target.The test Move to Production is repeated until it runs smoothly. A New Copy of Production is created for everytest Move to Production pass and is the new Target for each pass.
When you are ready for the final Move to Production pass, you freeze your production database andincorporate the modified objects from your most recent upgraded Copy of Production into the productiondatabase itself. Once again the upgraded Copy of Production (from the test move to productions) is yourSource and your production database is the Target.
