Abstract: A system and method for facilitating a migration engine to migrate data items in a data directory from a source system to a destination system over multiple migration passes are disclosed. A state file can be used to track migration states of data items during the life cycle of the migration. The state file can be generated and updated by a plugin to the migration engine. During a migration pass, the state file can be loaded into the memory to influence the migration by the migration engine. Prior to the migration pass, migration profile specifying one or more migration actions can be invoked by a migration routine. The invocation of the migration profile can cause the state file to be modified to perform the migration actions accordingly.

Abstract: A backup, search, and restore service is provided. The service can be achieved through a backup system, and a search and restore server. A user can be enabled to initiate a search request for one or more data items. A search can be performed by the search and restore server using metadata for the data items backed up by the backup system to return the one or more data items. The metadata for the data items can be generated by the backup system when data items are backed up by the backup system. The backup system may back up the data items on an incremental basis. The user can be enabled to select a data item in the one or more data items for restoration on the data system. Header information of the selected data item can be obtained from the data system to determine whether the restoration is necessary.

Abstract: Systems and methods are provided for automatically configuring an email client during a migration process. An client-side assistant can be deployed to an end-user's computer via a migration platform. After being deployed to a particular client computer, the client-side assistant can be configured to obtain user information to identify the end-user associated with the client computer. After identifying the end-user, destination system information regarding the end-user can be pushed to client computer for inclusion in new configuration information for the email client. Before generating the new configuration information, user credential for logging into the source system can be obtained. The client-side assistant can be configured to cause the destination system to confirm this credential. After generating the new configuration information, the client-side assistant can instruct the client-side assistant to use the new configuration information to at a specific time and date.

Abstract: Technology is generally described for automating the project management and execution of data migration from a source email system to a destination email system. In some examples, the technology can include receiving a domain name of a second computing system; obtaining domain name system (DNS) records for the received domain name; determining an email hosting provider for the second computing system; determining, by the processor, based on the obtained DNS records, an email system service type of the source email system on the second computing system; discovering mailboxes and message delivery rules of the source email system; displaying customization options for migrating discovered source email system mailboxes; migrating data items from the source email system to the destination email system; and managing migration of data from source email system client computing devices to the destination email system.
