I have been using version 2.1.7 of Neo4j since long and now wanted to upgrade it to 3.x. For that I found out this link Long upgrade path 2.1.x -> 3.5 which suggest to first upgrade to 2.1.x latest (which I think is 2.1.8). But I cannot find any download link for 2.1.8 version. Where can I download that version or any older version of NEO. Thanks!
You should find what you want here: https://github.com/neo4j/neo4j
But I really recommend that you create a new database with the latest version of Neo4j and import your data into it after
You can also go to the download center and change the version number in the url
