Mail data migration method

Abstract

The present invention relates to a data migration method for mail, which comprises the following steps: the protocol service transfers the normal request sent by the user and merges the data migration request to the data source server; the data source server returns the requested data to the protocol service, and the protocol service converts the normal The data returned by the request is sent back to the user, and then the data is encapsulated into a data stream; the data stream is transmitted to the target server by the protocol service; the target server parses and restores the data stream to obtain the data to be migrated. The mail data migration method provided by the present invention can encapsulate characteristic information according to needs to meet user needs; there is no need to stop service switching during the migration process, which can avoid mail data loss and affect normal use of users; historical mail data migration priority in the migration process Reduced, the subsequent migration can be split or postponed, which can reduce resource consumption; the migration process is fully controllable, and the migration operation can be stopped or rolled back at any time to protect data consistency throughout the entire process; the migration has a long time span, which can provide sufficient data for end users. buffer time to get used to the new system.

Description

technical field [0001] The invention relates to the technical field of Internet data transmission, in particular to a method for migrating mail data. Background technique [0002] E-mail is a very widespread application in the Internet age. E-mail services are provided by different vendors, and services of different brands have relatively independent protocols to realize different information flow processing and various data flow storage methods. During the replacement process of the old and new mail servers, users need to retain the original historical data, which requires the server to transfer the original mail-related data and original user-related data and ensure that it can continue to be used by users. [0003] Most of the existing email system services are implemented based on the IMAP protocol standard and the POP3 protocol standard. Users access the mail server from the client or access the mail server from the browser to perform a series of mail operations based ...

AI Technical Summary

Problems solved by technology

[0006] 1. Based on the inherent standard protocol migration, it is necessary to provide user authentication username and password. If it is operated for all users, it will be difficult to collect account information. If all users are changed to a unified password, it will affect user use or even leak

[0007] 2. It is necessary to migrate historical emails first before performing data incremental operations. Huge historical data will take up time and resources

[0008] 3. The data increment operation process needs to be shut down, which affects the user's use

[0009] 4. Convert emails based on the inherent protocol, the data flow is fixed and uncontrollable, and cannot meet the diverse conversion needs of users

[0010] 5. The migration process cannot be paused or rolled back, and the fault tolerance rate is low

[0011] 6. The old and new systems must be switched at one time, otherwise incremental migration will be performed again, and it is difficult for users to quickly adapt to the new system, resulting in a high failure rate
