Migrate old redmine data to new version
I got a pretty old Redmine on an old Centos which I'd want to migrate to a fresh install.
Is it possible to export the data from 3.3 and import it to 4.2?
Current version data:
Redmine version 3.3.3.stable
Ruby version 2.2.2-p95 (2015-04-13) [x86_64-linux]
Rails version 184.108.40.206
Database adapter Mysql2
as long as your installed plugins are supported in your new Redmine everything should work fine.
The upgrade process is described in the wiki article: RedmineUpgrade
I would highly recommend you to create a backup of your database and files first, just to be safe. ;-)
thank you for your response :)
However, update is not an option as they system already went EOL.
I need to migrate it to newer system.
That's why Im asking if there is a way to use the 3.3's data in a fresh install?
The upgrade process on a new machine is not very different from the one described in the wiki article.
As long as you have a copy of the database and your attachments you can move the data to the new installation, replace the existing database of the new installation with the old one and perform a database migration.
That shold be it.
