A system for upgrading an application running on a virtual computing instance (VCI) can include a processing resource, a memory resource, and a VCI manager. The VCI manager can be executed by the processing resource and the memory resource and can be configured to cause a first VCI that is running the application to be copied as a second VCI, cause an updated version of the application to be installed on the second VCI, and cause a private network to be generated between the first VCI and the second VCI. The VCI manager can be further configured to cause data to be synchronized between the first VCI to the second VCI via the private network and cause the application running on the first VCI to be deactivated and cause the updated version of the application to be activated on the second VCI.
