What is not working? There might be only one issue with not setting the HTTPS for your site.
You can export all credentials and workflows to file and import them later.
I did an update and from then on I could not access the new version through the domain name anymore and I wonder how this could happen to find out how to fix it.
In the meanwhile I did setup a new server and now try to import the credentials and workflows and how they will work well since the users they have been runned with would have a different User ID I guess
