Migrate from any version of Replication Server used with EnterpriseConnect Data Access (ECDA) for Oracle to Replication Server with ExpressConnect for Oracle (ECO).
The core functionality of ECO and ECDA for Oracle is identical. However, ECO functionality is preconfigured and tuned to best suit the usage of Replication Server with replicate Oracle database. The only reason to use ECDA for Oracle over ECO is if the ECO limitations are prohibitive for migration. Any new Oracle replication scenarios should use ECO.
