1. A computer-implemented method of transferring a partition function, the computer-implemented method comprising:
separating, as part of transferring the partition function from a source system to a remote multi-tenant target environment, physical and logical input/output (I/O) configuration settings of a partition image on the source system, wherein the logical I/O configuration settings are separated from the physical I/O configuration settings, and the logical I/O configuration settings are part of a subset of an input/output definition file and include one or more logical device numbers of one or more devices;
moving the logical I/O configuration settings from the source system to the remote multi-tenant target environment comprising a plurality of target systems;
selecting a dedicated target system of the remote multi-tenant target environment;
adding physical information about hardware and connections of the dedicated target system to the logical I/O configuration settings;
activating the logical I/O configuration settings combined with the physical information in the dedicated target system; and
starting an operating system with the activated logical I/O configuration settings, wherein the partition function is transferred.
