Upon completion of any migration prerequisites, you should proceed with the following installation and migration checklist, paying particular attention to the guidance that is directed at installations that have had OAM installed previously.

Important: The term migration means to upgrade from one version of DFSMS to this current version. This assumes that you were previously using OAM for storing objects and that you will continue to use OAM for object storage upon installation of this current version or release. The term installation indicates that you have not installed OAM in any of the previous releases of z/OS, and are therefore installing OAM for the first time with this version of the product.

Table 1 outlines the steps required for a new installation or migrating up from a previous version of DFSMS. These steps are discussed in detail in this topic.
