Neo4j Load Error: Caused by: java.lang.IllegalStateException: Can not read store version of database about neo4j HOT 3 CLOSED

Hey @GSTovey , looks like your dump was created on a version before 4.4. It is not supported to go directly from a version before 4.4 to 5.x.
You need to start a dbms of neo4j version 4.4, load the dump there and start the database with dbms.allow_upgrade=true set which will make the database migrate on the start up. And from there you can follow the 4->5 migration path to get your database into your 5.15 instance

For the dump -> 4.4 it is like this section but with load instead of restore https://neo4j.com/docs/upgrade-migration-guide/current/version-4/supported-paths/#restore-user-db
For 4.4->5 the documentation is here https://neo4j.com/docs/upgrade-migration-guide/current/version-5/migration/

Thanks for your reply!
It is indeed because my software version is too high that this error occurs, when I switched to a lower version of neo4j, everything ran normally.

Great that it solved the problem 🎉
I'll close this issue then, feel free to create a new one if you run into more problems
