Under correct operation, data migration will not lose the original content.
Backup the original data
Before migration, be sure to back up the original website's database and files. This is the most basic safety measure to prevent accidents during the migration process.
Verify in the test environment
Perform a migration rehearsal in the test environment to confirm the integrity and correctness of the content and format. Proceed with the formal migration after verification passes.
Step-by-step migration
Suggest migrating step by step: first migrate the category structure, then migrate the article content, and finally migrate images and other resources. Reduce the risk of errors.
Data validation
After the migration is complete, compare the number of contents, classification structure, image links, and other aspects between the original website and the new website to ensure data integrity.
Rollback preparation
Maintain the original website's running environment, confirm that the new website is running properly before taking down the old site. If there are any problems, you can quickly roll back.
