Check Details
Migration scenario
Source database versions earlier than PostgreSQL 10.x (such as 9.x) do not support full + incremental migration. If an incremental migration task is configured for the source database, the verification will fail.
If the source and target database versions are inconsistent, there may be some compatibility issues and the task will report a warning. You need to read the compatibility report of each version to check whether your business has used incompatible features.
Sync scenario
Source database versions earlier than PostgreSQL 10 do not support data sync. A data sync task requires that the target instance version be later than or the same as the source instance version.
If the source and target database versions are inconsistent, there may be some compatibility issues and the task will report a warning. You need to read the compatibility report of each version to check whether your business has used incompatible features.
