> 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.
