The invention discloses a method for data migration of a non-relational database HBase. According to the method, by reading configuration file information of users, data within a time period designated by the users are migrated from an old HBase cluster to a new HBase cluster. The method has the advantages that by designing RowKey, group information and time information of the data are embodied on the RowKey, and whether the data corresponding to the RowKey are within a migration time range designated by the users can be directly identified by scanning the RowKey during data migration; groups serve as data migration units, every group serves as a check point, the range of the non-synchronous data between the old HBase cluster and the new HBase cluster can be rigidly controlled within one group when abnormal conditions occur, and time required for restoring data synchronization is reduced; log information is recorded in the data migration process to be used for treating the abnormal conditions in the data migration process, synchronization of the data between the old cluster and the new cluster is guaranteed, and data migration between the HBase clusters can be finished accurately and efficiently.

InactiveUS20120102069A1Accurate MigrationDigital data information retrievalDigital data processing detailsNetwork management applicationApplication software

In a system for migrating data between document management applications, if an inheritance setting of an access right to a folder in a source document management application is a first inheritance setting for inheriting an access right to a parent folder, the inheritance setting of the access right is changed to a second inheritance setting for setting an access right exclusively for the folder while the same access right as the access right to the parent folder is set. Then, the folder is migrated to the destination document management application. If a hierarchy including the folder to be migrated exceeds an upper limit on the number of hierarchies in the destination document management application, the folder is stored in a shallower hierarchy in the destination document management application.
