A system and method for migrating state data from a source computing platform to a destination platform, such as for migrating state data from one computer to another computer. Pluggable modules collect state on a source platform and transport it to temporary storage as state objects that are independent of any particular destination platform. For example, a state object may contain the information that represents a file on a source machine, while another state object may contain a piece of registry data on that machine. At the source platform, modules provide state data gathering and analysis that collect the data into the state objects. A transport module transports the data to storage accessible to the destination. At the destination, the state objects are applied by pluggable modules to the destination platform. The object data can be adjusted, translated and/or merged with destination state data as appropriate for the destination platform.
