after build and running the webapp while pointing to my existing 1.9.1 db:
caused by: org.neo4j.kernel.impl.storemigration.UpgradeNotAllowedByConfigurationException: Failed to start Neo4j with an older data store version. To enable automatic upgrade, please set configuration parameter "allow_store_upgrade=true"

rabbithole uses 2.0 in its current version. do you really want to upgrade your store to 2.0? If not, you might be able to just change the dependencies in rabbithole's pom to point to 1.9.x. I don't think it's doing anything special, but michael would know.

In your neo4j.properties you add:

allow_store_upgrade=true

Note: There is no going back to 1.9 after this.

Hi,
I just run into the same issue.
I changed pom.xml from:

<properties>
<neo4j.version>2.0.0-M04</neo4j.version>
 </properties>

to

<properties>
<neo4j.version>1.9.1</neo4j.version>
 </properties>

but I got the same error as before.

I can't find the neo4j.properties neither in the db folder nor in rabbithole/.
Any suggestions?

Thanks,
Immanuel
