Migrate from 3.3.3 to 4.1.1?

Added by John Reynolds over 3 years ago

Hello,

We used Redmine a lot from 2011 through 2015, and then had to stop. But I've kept the VM around... it's Ubuntu 16.04 and Redmine 3.3.3.

Is there any way to get "current" with my data and attachments not being lost in the process by chance? I'm up for building a new Ubuntu 20.04 and the like if needed, etc. I'm not sure of the steps I would need along the way... i.e. how far I could upgrade before ruby/rails on 16.04 would be problematic, etc.

Thank you,
--J

Hello,

You shouldn't have any problem, but make a copy of the WV and:
1º Change the code for the new version of Redmine
2º Run rake db:migrate to execute the migrations and leave the database in the current state

Greetings,
Adrian
