FALCON-1333 (Instance Search feature) requires Falcon to use titan-berkeleyje version 0.5.4 to support indexing. Up until version 0.9 - Falcon used titan-berkeleyje-jre6 version 0.4.2. GraphDB created by version 0.4.2 cannot be read by version 0.5.4. When attempting an upgrade, I realized that entity and instance lineage data created in 0.9 version could not be read by Falcon in 0.10 version.
The only solution seems to provide a tool to do the following
- Use 0.4.2 version of titan-berkeleyje-jre6 to read the berkeleyDB based graphDB and create a JSON file with all data.
- shutdown falcon-0.9, upgrade Falcon.
- use 0.5.4 version of titan-berkeleyje to read JSON file and repopulate berkeleyDB based graphDB.
- restart falcon-0.10
I will work on the tool, and update release-notes, upgrade instructions accordingly.
