A computer-implemented method that includes determining that a first version of an operating system (OS) is updated to a second version of the OS. The method further includes determining that an application does not support the second version of the OS. The method further includes associating the first version of the OS with the application as a base OS. The method further includes invoking the application on the base OS by generating an isolated instance running the base OS on a user device, where the user device simultaneously runs the second version of the OS.
