How to migrate an old database to a new bitnami-installation
We have installed redmine 4.2.3 with the bitnami-Installer on an windows machine.
On another machine, we have an old 4.0.1 installation on linux.
What are the exacts steps to migrate the old database (and files) to the new machine?
We simply loaded the new database, but didn't succeed so far.
Is there a separate Upgrade-Step required for the database (to upgrade the scheme, etc.)?
Any help welcome.
yes, you are right. You have to update your database scheme to the new version.
Please have a look at the article RedmineUpgrade in the wiki.
Step 4 describes the database migration process.
