An EPi 7 version of Epinova.Webparts.Providers.SpecializedProperties hasn't really been released publicly, just been used internally to upgrade our own customers.
Contact me by mail arild.henrichsen(at)epinova.no and I'll try to dig something up for you.
Did you upgrade the WebPart provider?
The code contains a tool for converting webparts to blocks as well :)
Thank you for your quick and helpful answers :)
Does anyone have any experience with upgrading an episerver 6R2 site with webparts to episerver 7? I'm currently running in to the following error message in the browser:
I've searched the error and tried changing occurencies of PageDefinitionTypePlugin to PropertyDefinitionTypePlugin with no luck.
It is clear that we should make the move from the webparts-plugin to blocks in episerver 7. What would be the quickest solution to this without loosing data?
Thanks in advance :)
