Check Details
The source database version cannot be later than the target database version; otherwise, an error will be reported with the error details: "Check if the database version numbers are consistent.".
Fixing Method
If a data version check error is reported: "Check if database version numbers are consistent," please verify the database versions of the source and target instances. A later version instance cannot migrate to an earlier version instance. For example, a source instance of version 2012 cannot migrate to a target instance of version 2008. The target instance's version must be later than or equal to the source instance's version for migration to proceed. You can use the console's Adjusting the Instance Version feature to upgrade the target instance's version.
