Automated analysis and recovery of localization data

Recovery of localization data is provided between versions of a software product. A first resource is identified that is associated with a first version of the software product. A second resource is identified that is associated with a second version of the software product. A first resource identifier associated the first resource is different from a second resource identifier associated with the second resource. The first resource is mapped to the second resource when the second resource is found to be a shifted version of the first resource. The localization data corresponding to the first resource from the first version is migrated to the second version and the localization data is associated with the second resource from the second version when the second resource is a shifted version of the first resource.
