So this is a bit of a vague question and I apologize but here goes nothing.
I am in the process of creating a SP2013 test farm that is an exact copy of our SP2010 production farm. When I mount the main content db for our main site collection I get a missing feature ID error. Here is the problem I need help with...
The solution that should have this feature is deployed to the farm already, however, as I was not working here when these solutions were made I don't know if I'm deploying the correct .wsp file. There are about 8 revisions so I naturally deployed the latest one.
So... 1. Would feature ID's change from version to version? 2. Is there a way to see which .wsp is deployed to my production farm.
Thanks for any help!
Featuer ID will not change from version to version. you can see installed features from template/feature folder under SharePoint Hive (either 15 or 14 hive based on your sharepoint version).
Hope this helps.
