How to upgrade existing graphenedb instance?

How can you upgrade an existing graphenedb instance to the latest version?

I tried:

heroku addons:add graphenedb --version v220
Adding graphenedb on myApp ... failed
!    That type of add-on can only exist once per app and it already exists for myApp.

Or is it not possible and should I migrate the data to a new instance with the latest version?

BTW, I also tried heroku addons:upgrade. That was NOT what I was looking for!

Solution

  • I'm Alberto, one of the founders of GrapheneDB.

    As you have noticed, $ heroku addons:upgrade graphenedb:plan will upgrade the plan, not the version of Neo4j.

    Currently it's not possible to upgrade the version of Neo4j through the UI or the Heroku CLI. There are two options:

    1. Export your data store using the export feature in the admin tab. Download a copy. Remove the add-on, add it again with the new version of Neo4j and perform a restore (admin tab again) with the downloaded store file.

    2. Open a support ticket specifying the database and the version you'd like to have and we'll do it for you.

    Thanks for using GrapheneDB!
