Abstract
Technical solutions are described for performing a live update of an operating system. An example method includes cloning an original root volume group associated with an operating system instance executing in a first logical partition to generate a cloned root volume group for booting a second logical partition. The method further includes applying the update to the cloned root volume group, and booting the second logical partition. The method further includes migrating an application instance, from the original root volume group to the second logical partition. The migration includes creating a network tunnel between the first and second logical partitions, and restarting the application instance on the second logical partition. The migration further includes forwarding data directed to the application instance on the first logical partition to the application instance on the second logical partition, and assigning a network address of the first logical partition to the second logical partition.
