4.3.3 Import at the time of version upgrade
If you import repository information whose version is newer than the current repository information, the version of the repository is automatically upgraded at the time of import.
If the business process or the service adapter, which is currently deployed, is deleted in the repository information to be imported, an error occurs in the import operation at the time of version upgrade. If an error occurs, export the current repository from the operating environment and import it in the development environment. After that, export the repository whose version is upgraded in the development environment from the development environment and import it in the operating environment.
For details on version upgrade, see "Appendix G. Migration from an Old Version".
