Migration considerations for z/OS

When upgrading from a previous level of Host On-Demand, to Host On-Demand V14.0, you need to consider the previous customization. Unlike previous migrations, from HOD v12.0 onwards, you cannot install HOD on top of a previous level of Host On-Demand because the Installation Manager is used to install the HOD Versions from HOD v12 onwards, and you need to start with an empty file system. After HOD V14.0 is installed, you can copy your previous private directory to the new private directory for any Groups and Users and sessions previously defined. Then use the pax or the tar command to copy your existing private directory into the HOD V14.0 File System. Refer to Backing up the private directory.

As for the previous clients created with the Deployment Wizard, you need to install the Deployment Wizard on a Windows computer. Then edit and redeploy the client to the HOD V14.0 server. Refer to Installing the Development Wizard from the z/OS server.
