I am trying to move a site from DNN 3.3.7 up to 4.9.0. Everything works perfectly, except about 10 pages. These pages have an old vendor module which allows you to share a module (typically html module) across multiple portals. So you build it in one portal and then let it point to other portals, typically child portals.
So for example: There is a contact us module which is shared between 3 child portals, making an update in the main portal / module feeds down to the other ones.
The current module seems to actually just duplicate the module, and when you choose edit loads up the content of the main module, and then reduplicates the changes to the other portals. Sort of a copy paste method, but automated for the portals you push the module to.
I can't get a good feel for who the original vendor was. I have looked in their module folders, but there is no sort of text file or manifest identifying them. All I have is the module names and their leading abbreviation. NMH-<moduleName>
It would be nice to find a replacement module for this one, or find the vendor and see if they have an updated version.
Thank you all for the help.
