How to move the previous issue information from old webside to the new system OJS 3.0?

Hello, our journal is trying to adopted the new system of OJS 3.0 now, I wonder if I can move the previous imformation expecially the previous issues including paper files to the new system.I find we can import issues only in the future issue penal, but the articles can only import through submission panel to list in the content of issues, and must through the submission process, the author name can not be change, so it is hard to import previous issues through this method. Can you give me some advice to achieve my goal to add previous issues?

What application are you using?
OJS 3.0

Hi @Rido

Can you clarify what you mean here? Are you digitizing physical files and planning on uploading them to OJS?

What method are you using to add the articles currently?
What specific version of OJS are you using (e.g. 3.4.0-3)?
