1. A computer-implemented method comprising:
receiving, by one or more processors at a first storage site, a request to migrate a set of file(s) from the first storage site to a second storage site;
identifying, by one or more processors at the first storage site, a stub file within the set of file(s) to be migrated within a hierarchical tiered storage system, wherein the stub file is linked to a source file located at a storage site that is not the first storage site or the second storage site and wherein the first storage site is not compatible with the second storage site;
creating, by one or more processors at the first storage site, a virtualized environment containing the identified stub file and content associated with the first storage site;
integrating, by one or more processors, both the first storage site and the second storage site with the virtualized environment using the identified stub file;
generating, by one or more processors, an integrated virtualized environment in response to integrating both the storage site and the second storage site with the virtualized environment, wherein the integrated virtualized environment includes the identified stub file and the content associated with the first storage site; and
migrating, by one or more processors at the first storage site, the integrated virtualized environment from the first storage site to the second storage site in response to integrating both the first storage site and the second storage site with the virtualized environment, wherein upon migration, the source file is accessible at the second storage site via the stub file contained in the migrated integrated virtualized environment.
