Upgrading search subsystems

This section provides information on how to migrate the search subsystem during an upgrade to Alfresco One 5.0.
Important: The Lucene search subsystem is not available on Alfresco One 5.0.
Important: During an upgrade, Solr 4 needs to reindex the entire repository. While reindexing is in progress, you may use Solr 1 for basic search functionality - new functionality enabled by Solr 4 (such as filtered searches) will not be available, and you may encounter other issues with search capabilities.

Although the Solr 1 search subsystem is available on Alfresco One 5.0, it is only supported while Solr 4 is in the process of reindexing the repository. Only Solr 4 is fully supported on Alfresco One 5.0.

This section describes the migration path of the following two examples:
  • Upgrading from Alfresco 4.x with Lucene to Alfresco One 5.0 with Solr 4
  • Upgrading from Alfresco 4.x with Solr 1.4 to Alfresco One 5.0 with Solr 4
