1. A method comprising: mounting, by one or more computer processors, a computing device to a target instance, wherein the computing device stores one or more virtual disks of a source instance, and wherein the target instance includes one or more local disks; detecting, by the one or more computer processors, one or more parameters of a disk layout of the source instance, wherein the one or more parameters of the disk layout include at least a disk ordering and a primary disk; matching, by the one or more computer processors, the one or more parameters of the disk layout of the source instance to one or more parameters of a disk layout of the target instance; based, at least in part, on the matching of the one or more parameters of the disk layout, attaching, by the one or more computer processors, the one or more virtual disks of the source instance to a corresponding one or more local disks of the target instance, wherein the one or more virtual disks of the source instance are attached as one or more flat files; and copying, by the one or more computer processors, the one or more flat files to the corresponding one or more local disks of the target instance.
