Hi John,

we are very interested in a step by step instruction. So if you can provide one, many thanks and kudos.

I believe it mainly depends on the version of redmine that is installed.

It is fairly easy if the redmine version is rather old (< 1.2 should be safe). Then it is just installing OpenProject and after having dumped the current redmine data into the database used for OpenProject, running the migrations. First those of OpenProject 2.4, than those of OpenProject 3.0.

When a newer redmine is installed, one has to rollback the redmine migrations until the db schema is one that can be migrated up from by OpenProject. Then again, migrate to OpenProject 2.4, and after that to OpenProject 3.0.

With plugins installed, there will be hundreds of alternative routes.

We have written down some of what we did when migrating from ChiliProject installations:
https://www.openproject.org/projects/openproject/wiki/Migration_15_to_30
https://www.openproject.org/projects/openproject/wiki/From_Chilliproject_to_OpenProject

Hope that get’s you started

Jens

Hi Jens

Thank you for this.

I’ll investigate this further and see what progress I can make.

Regards

John

Hi Jens

I have completed the migration process and am ready to write a Wiki page on this.

How would you like me to proceed? Do you need to grant me editor access?

Thanks

John

Hi John,

I granted you Community Member rights, thus, you should be able to create a new wiki page by now.

Kind regards,
Hagen

Hi Hagen

I’ve written the Wiki page and attached it to the Migrations here https://www.openproject.org/projects/openproject/wiki/Migration_paths

Please feel free to correct/edit.

Thanks again

John

Hi John,

first of all thanks a lot for the detailed description!

We would like to publish a news article about your migration steps. Are you fine with that?

Hagen

Hi Hagen

Yes, no problem.
