Abstract

The embodiment of the present invention relates to the field of computer technology, and discloses a data migration method and system. The data source migration method includes: slice the old system data to obtain data slices; import the data slices into the new system in batches; The order of the sequence numbers of the requests is to redo the data corresponding to each write request in the new system in turn; wherein, the above-mentioned pre-recorded write requests are written into the old system and the new system at the same time. The embodiment of the present invention can seamlessly import the data of the old system into the new system without prohibiting writing to the old system, and the data of the new system can be restored to the latest through the redo technology, which can realize the background that the user is completely unaware of Data migration, and reduce the risk of new and old system data import, simplify operation and maintenance operations.

Description

Technical field [0001] The invention relates to the field of computer technology, in particular to a data migration method and system. Background technique [0002] In the process of replacing the old and new systems of User Generated Content (UGC) services (such as Weibo), it is inevitable to encounter data migration problems. However, how to transfer the old system data as far as possible without affecting users Under the circumstances, the complete migration to the new system is a problem that has always been urgently needed to be solved. [0003] In the prior art, a common data migration method is to prohibit writes from the old system (that is, prohibit user write requests), then import the old system data into the new system in turn, and then route the user write requests to the new system to continue serving. However, this data migration method is the most crude, and the old system must be banned from writing, and the banning time depends on the data migration time. The lon...
