Is it possible to run plugins built for CMS 5 R2 in CMS 6?
CMS 6 is designed to be backwards compatible to CMS 5 R2. So plugins made for CMS 5 R2 should work with CMS6 as well. There will be some slight breaking changes, but those will be documented and hopefully wont effect old plugins.
Per GunsarfsEPiServer Development Team
The only non-working issue I can see without testing is that plugins to the old EPiServer CMS 5 editor will not work in the new TinyMCE editor in CMS 6. (If you have very important plugins for the old editor you can keep the old editor in CMS 6 until you have made new plugins for Tiny and do the change of editor then. )
Thanks for the replies so far!Is there anything more to be done, than to install the selected plug-in in EPiServer CMS with existing tools. We have tried to install a plug-in for ManageLanguages, it does not appear in Admin mode. We have downloaded the source code and compiled it against EPiServer CMS 6 .dll files.Hoping for some guidance on the matter.
There should be no difference than CMS 5 R2 as far as I know. So first, check that the dll containing the plugins exists in the site's bin folder. If it does, go to Admin Mode -> Config -> Tool Settings -> Plug-in Manager and check the the assembly shows up there and that the plugins are enabled.
That could give some clues as to where it's going wrong.
