The problem is that you need to move the content, user accounts, ratings, etc. from one system to another. The existing system has to had an API to export that information in a format that the new system can understand. If you have that, then it is easy, the problem is most systems out there do not have that :) Situation is a bit better with extremely popular projects for blogs or forums, like Wordpress or phpBB, which have an ecosystem of exporter/importer tools.

- ridruejo 15y agoSorry, that's nonsense. Each one of the systems is going to have a different schema and constraints for users, posts, comments, votes, that most likely will not have a one-to-one mapping.
- tommi 15y agoSomething - yes. Something which implements everything required and is tested - not likely. There's a huge difference between converting data from your little hobby and converting the vital knowledge of your company. It's different because it's more mission critical - you don't want to screw it up. It's also different because the bigger dataset is likely to have some customizations and other "small" stuff which tends to matter in big perspective. You might be okay for losing e.g. votes if it's a small data set, but you really want it in with a big one.
