The source and destination environments must use the same release number. For example, if you use release 11.1.1.1 of Shared Services to export artifacts, you must import using release 11.1.1.1. Using different releases to export and import artifacts is not supported.
The source and destination must use the same user directory.
When performing a migration, if the source artifacts have an earlier time stamp than the destination artifacts, the artifacts will not be migrated. To migrate such an artifact, update the source artifact so that the time stamp is newer than the destination. The artifact will then migrate.
Source and destination applications must be registered with an instance of Shared Services. (Note that EPM System supports Lifecycle Management of applications in isolated environments with separate instances of Shared Services in each environment.)
During export, Shared Services source applications must be running. During import, Shared Services destination applications must be running.
