Experience in cypher export from neo4j 2.2.2 to latest version?

Hi, all --
We're on an academic project and we would like to adopt a dataset out of neo4j 2.2.2 onto the latest neo4j version for use on a server. We only seem to be able to find upgrade paths from 3.5.x -- any recommendations on if we should try to start this with a cypher export and then reimport? Has anyone had experience with this?
