Long upgrade path 2.1.x -> 3.5 - #3 by ryan.boyd

Suggested upgrade path : 2.1.4 -> 2.1.8-> 2.3.12 -> 3.3.9 -> 3.5.5->3.5.latest→ 4.0.latest → 4.1.latest → 4.2.latest**

But the challege we are facing is the older versions of neo4j installers are no longer available.

Hi,

One possible way to upgrade, would be to take a backup/dump of the database from the current version of your Neo4j, save it. Then set up the latest version of Neo4j as a fresh database and import the data back into the db on the latest version.

Since 2.1.4 is a very old version and has a lot of upgrades happened since then, not sure if there is any direct way to upgrade as a lot of background structure of Neo4j architecture and working has also changed between 2.1.4 and latest 4.x.

Regards.

I dont know if the backup approach would even work

Neo4j 2.1.4 is 7 yrs old Neo4j 2.1.4 - Neo4j Graph Database Platform.
