upgrade redmine 1.1.3 to 4.1.1

I have old redmine version 1.1.3 on Centos5.
And I want to upgrade it to redmine 4.1.1 or migrate the project or database to the new version.
Could you have the suitable plan?
Thanks.

Hi, I've had such scenario a few days ago ;-)

I updated to each latest possible major version:

1.x.latest
2.x.latest
...

and so on. Migrations worked so far without problems except some plugins which were not available anymore.
