Abstract

A method for migrating a workload from a first to a second computer system. The first computer system initiates a first data link from the first to a third computer system and the second computer system initiates a second data link from the second to the third computer system. The first computer system reads the workload to be migrated on a block device level from a first storage device of the first computer system, divides the workload to be migrated into data blocks of a predefined size and uploads data corresponding to the data blocks to the third computer system. The second computer system downloads data corresponding to the data blocks from the third computer system and writes the data blocks to a second storage device of the second computer system, such that an identical copy of the workload to be migrated from the first computer system is created.

Dependent claims

Method for migrating a workload from a first computer system to a second computer system, the first and the second computer system being connected to a data network, the method comprising:

setting up a first data link via the data network from the first computer system to a third computer system and a second data link from the second computer system to the third computer system, wherein the first and the second data link are initiated by the first and the second computer system, respectively;
reading, by the first computer system, the workload to be migrated on a block device level from a first storage device of the first computer system;
dividing, by the first computer system, the workload to be migrated into a plurality of data blocks of a predefined size;
sequentially uploading, by the first computer system, data corresponding to the plurality of data blocks from the first computer system via the first data link to the third computer system;
downloading, by the second computer system, data corresponding to the plurality of data blocks from the third computer system to the second computer system via the second data link;
writing, by the second computer system, the plurality of data blocks to a second storage device of the second computer system, such that an identical copy of the workload to be migrated from the first computer system is created.
