Methods and systems for performance measurements of a program are provided. An execution trace of the program may be captured and stored. The stored execution trace may be replayed in an offline mode. Performance measurements for the program may be determined based on the replaying of the execution trace in the offline mode.

Performance diagnostics via offline replay

Migration of data relevant to, or associated with, one or more users from a prior operating system installation to a new operating system installation can be performed with reference to an archive of some or all of the data on a storage media made prior to the installation of a new operating system. Manifests associated with operating system components can be referenced to identify data to be transferred from those operating system components to new versions of those components. Independently generated manifests can also be referenced to migrate the files and data for one or more application programs, such as popular or commonly found application programs. User data and files to be migrated can be identified by loading registration database files from the offline operating system in the new operating system, or otherwise parsing a similar construct from the offline operating system.
