Migrating from Redmine 1.1.3 to Redmine 4.2.1
Hi,
We've been using Redmine (Redmine 1.1.3.stable.5937 (MySQL)) successfully since 2010 and would like now to migrate to a new version.
We installed a distribution from Turnkey v16.1 with following specs:
Does anybody have experience with such a migration?
I'm afraid a database export-import won't succeed as table structures probably have changed.
One option could be to export the data and reimport using the REST interface but it means a lot of work.
Any advice will be appreciated!
Many thanks
Denis

You should be able to migrate your existing database (including all of your existing data) as part of the code upgrade.
See RedmineUpgrade for the detailed steps to upgrade an existing Redmine installation.
Make sure you have full working backups of your existing installation and database before starting the upgrade so that you can go back to your old working state in case there are any problems. It may also be a good idea to first test the migration in a test environment to make sure that everything runs smooth as the step from Redmine 1.1 to 4.2 is rather large.
Finally, I'm not sure how TurnKey updates their distributed packages (given that they are not directly affiliated with Redmine and just distribute Redmine's code in a different format), but Redmine 4.2.1 is rather old and contains several known security issues. See https://plan.io/redmine-security-scanner/versions/4.2.1 for details. If possible, you should at least upgrade to the latest supported 4.2 version, namely 4.2.10, or even better to the latest version 5.0.5.
