Embodiment Construction
[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0044] The present invention is mainly to set a status mark for the original data according to the migration state of the original data when the original data is migrated; Execute the operation command.
[0045] figure 2 It is an overall flow chart of the data migration method of the embodiment of the present invention, such as figure 2 As shown, the process includes two parts, wherein steps 201 and 202 are the data migration part, and step 203 is the data service part.
[0046] Step 201, migrate the original data.
[0047]There are many specific processes for migrating original data. For example, one original data can be read and migrated at a time. After the migration is completed, the next original data can be read and migrated until all the ori...

The invention discloses a data migration method which is used for migrating initial data. During the migrating process of the data, a status mark is arranged for the initial data according to the migration state of the initial data; and when the operating command of a user to the initial data is received, the operating command is executed according to the status mark of the initial data. The invention further discloses a data migration system, a data migration server and a data interface server simultaneously. The method, the system, the data migration server and the data interface server candetermine the migration status of the initial data through the status mark, thereby determining to operate the initial data or initial data after being migrated, and avoiding the problem that ineffective operation can occur when the data are operated during the migration process of the data, so that a user still can use data service to operate the data during the migration process of the data; and the data service is not required to be stopped.
Description
technical field [0001] The invention relates to the technical field of data migration, in particular to a data migration method, a system, a data migration server and a data interface server. Background technique [0002] Data migration refers to the process of converting data from one medium to another or from one format to another, such as transferring data from one hard disk to another, or converting WORD format files to PDF format files, etc. For individual data, the migrated data cannot be used during the migration process, and the data can only be accessed or modified after the data migration is completed. [0003] Limited by the current technology, the speed of general data migration is not ideal at present, especially the migration of massive data, such as migrating a large amount of data in a database to another database. Due to the huge amount of data, it is very possible to complete the migration of all data It takes several days or even weeks. During this perio...
