I need to convert a concrete5 site to a WordPress site.
I can’t find any plugins on both sides. There might be a solution via a feed ex-/import but it does not support all the contents and images.
Is there any idea how to do this?
Migrating from concrete5 to wordpress
I don’t know of any pre-packaged solution for this. If there aren’t too many pages (under 50 or 100), your best bet is to do it manually — hire a temp worker for a day if you’re a developer with a non-trivial rate.
If there are hundreds or thousands of pages, though, then you’ll want to come up with your own automated solution. You can get some kind of XML representation of site content I believe via the Dashboard “backup site” functionality (not the “backup database” one). Or look into the concept of “Starting Points” in Concrete5 — there’s a free addon in the marketplace that lets you export site content in another XML format.
Then look into wordpress importers, and figure out how to transform the C5 output XML into whatever format your wordpress importer requires.
Best of luck.
