- Currently, GaussDB V2.0-8.0 Enterprise Edition, V2.0-8.100 Enterprise Edition, V2.0-8.200 Enterprise Edition, and V2.0-9.0 Enterprise Edition as the target database are available only for trustlisted users.
- When GaussDB is used as the destination database, its versions earlier than V2.0-2.7 are not displayed on UGO. If GaussDB V2.0-2.1 or V2.0-2.2 Enterprise Edition is used, migrate it to V2.0-2.7 Enterprise Edition. Instances of GaussDB in versions earlier than V2.0-2.1 cannot be migrated by UGO, so you need to upgrade the version.
