When migrating a database to a different server, data loss can occur due to incomplete transfers, compatibility issues, or configuration errors. buy cox internet   To prevent this, ensure thorough backups before migration and validate data integrity post-transfer. Use reliable migration tools, follow best practices, and test the migration process in a staging environment to safeguard against potential data loss.

Hello, 

Looking at the screenshot and your logs, it seems that your website version is 11.2.2.0, while the scanning service is on 11.4. 
We think the backup and restore steps mentioned in the article are not correctly followed. Could you please review it?
If any doubt, you can contact Lansweeper Support.
