Patent ID: 7937612

Claim:
A method of migrating a server, the method comprising: creating a block-based image of a storage device of a first server, the image comprising a bitmap; while the first server is hot-migrated on-the-fly and a second server is started during the hot-migration, executing a boot loader on the second server, and restoring, from the image, to the second server, those blocks of an operating system data that are needed to start the second server; modifying parameters of the second server's operating system based on a hardware configuration of the second server, to enable interfacing to hardware of the second server; using at least some of the image data as a local drive data of the second server; running the second server using the image data, the restored blocks of the operating system data and the modified operating system parameters; and while the second server is running, based on the bitmap, restoring unaltered portions of remaining data from the image.
