Migration Scenario
Full + Incremental migration requires both the source and target instance versions to be later than or equal to 10.0.
If the source and target instance versions are different, some special compatibility issues may arise, and a warning will be reported. Read the compatibility report for each version to check whether your business is using any incompatible features.
Synchronization Scenario
Versions earlier than PostgreSQL 10 do not support synchronization. The target instance version should be later than or equal to the source instance version during data synchronization.
If the versions are different, some special compatibility issues may arise, and a warning will be reported. Read the compatibility report for each version to check whether your business is using any incompatible features.
Fixing Method
Check the source and target databases according to the version requirements. If the source or target database version is not supported, upgrade the target instance version or use a database instance of a later version.
