Migrating search collections

When you upgrade to a higher version of WebSphere® Portal, the data storage format is not necessarily compatible with the older version. To prevent loss of data, export all data of search collections to XML files before you upgrade. After the upgrade, you must create a new search collection and use the previously exported data to import the search collection data back into your upgraded portal.

1. Document the configuration data of your portal site content source.
2. Delete the existing content source.
3. Upgrade your portal.
4. On the upgraded portal, create a new portal site content source. Use the documents configuration data.
5. Run the new portal content source.

   Portlets that were crawled before the upgrade, but do not exist in the upgraded portal, are not returned by a search.
