Replication and versioning—ArcGIS Pro | Documentation
Geodatabase replication is built on top of traditional versioning. During replica creation, versions from the source and target enterprise geodatabases are set as replica versions. Changes in these replica versions are exchanged during synchronization. Because the replica versions are linked, you can think of them as a way to extend the version tree to span multiple geodatabases.
The default version or any child version can be used as the replica version for the parent or child replica. Several replicas can also share the same replica version.
Note:
If you do not want to register as traditional versioning to be able to support the Geodatabase Replication functionality, then you can use the native RDBMS replication tools. Example: Oracle Data Guard, Oracle Golden Gate, SQL Server Always-On, PostgreSQL Slony.
I hope this answers your question.
