Abstract: Accordingly, software providers are quickly migrating enterprise applications to reflect this new framework. However, companies and enterprises today lack a reliable method of handling the migration and amongst the challenges they face is handling the sizing and partition of the legacy public folder hierarchy into the new public folder mailbox structure. Accordingly, it would be beneficial to provide users with a means to handle this mapping from the legacy public folder hierarchy into the new public folder mailbox structure. Further, the cloud software provider migration methodology requires downtime in the source public folders such that mail-enabled public folders are queued freezing these communications until the migration is complete. Further, if the migration process fails then it must be reattempted in full which is not feasible for most business as critical business workflows require the availability of the public folders.
