Organizing Archived Projects

Is there a good way to organize archived projects? When we use a template over and over again for a new client on-boarding we are amassing quite a list of archived projects. I want to keep a history of the project including assignees and completed dates. I have created a new Archived Projects Team for now, but is there no way to better organize them when they are archived (Folder, etc?). I guess the other method would be to print/export and then delete the project?

Maybe always use the advanced search to find an archived project and never dig by yourself? I have this kind of process for emails now: they all go to the same folder, I find them back using the search.
