MDS Export & Import

While migrating SOA composites from one instance to another instance, we also need to update the target system MDS.

To make sure that, the target system is having proper MDS artifacts, we can use Export & Import option available in EM console.

Steps to perform MDS export & import:
1. Login to Source system weblogic EM console. Expand SOA and right click on soa-infra. And select Administration --> MDS Configuration.
2. Click on Export Button on MDS Configuration screen and wait for 5-10 minutes.
3. After 5-10 minutes, the server will prompt you to save a zip file. Click on Save to save it into local machine.
4. After completion of zip file download, go to the location that where the file has been saved.
5. Select the zip file and extract it. Wait till extraction gets completed.
6. After zip file get extracted, 3 folders named apps,deployed-composites & soa will be created in the same folder.
7. Delete deployed-composites & soa folders.
8. After deletion, rename the zip file. For Ex: soa-infra_metadata--bkp.zip
9. Select apps folder and create a zip file.
10. Rename the zip file to soa-infra_metadata.zip
11. Login to Target system Weblogic EM console. Expand SOA and right click on soa-infra. And select Administration --> MDS Configuration.
12. Click on Browse button available under Import Section. A window will be displayed to select the zip file. Select the zip file created in step 10 i.e. soa-infra_metadata and click Ok.
13. Click on Import button to start MDS import to Target SOA server.
14. Wait till Import operation get completed. A confirmation message will be displayed on screen.
15. Go to Jdeveloper and create a MDS connection to SOA database and verify MDS artifacts.
