Abstract
A computer system has an OS running on it. The computer system has Virtual Execution Environments (VEEs—containers or Virtual Machines), an old OS (to be replaced), a memory area which has data needed for system restart and restore from the VEE. The VEEs are moved into snapshot and a new OS is loaded into the memory. The new OS launches and receives data needed for restore of the system from the snapshot. Then, the new OS activates the VEEs. Thus, the new OS is reloaded onto the computer system without a physical memory reset.
