On jBPM 7.9.0, and now on 7.10.0 there are a few tips on the jBPM welcome page, over to the right. Specifically, there is a bat and script provided in jBPM and found in the bin file. This script does a pretty good job of converting jBPM over to MySQL. However, the migration is not complete. There are some continued references to the H2 database in the Standalone.xml file. I see references to H2 when i inspect the start up logging for jBPM and finally.... and perhaps most irritating for me, When i look at a Project Process ( workflow ) in the designer i see that the "Persistence" options still say that they are using H2 for a Hibernate Dialect. I am not sure what this does or what really happens when the option is deleted in the Workbench Process Designer. I have run a few tests and i'm not sure i see bugs. All in all.. it is pretty nice to move jBPM over to MySQL. It seems to work well for the purposes of my Proof of Concept.
