Here is the problem. I've been given SharePoint 2010 farm with pretty huge web app, with large site collection, with custom features, some of which are paid and key required, which I don't have (namely NewsGator). And I have a task to move all this to different farm, to different db-server and to different domain.
I moved DBs, attached them, and even managed to install and activate most features with plain copying of "features" dir and running my ps script to install and enable them. Unfortunately that is not enough and something is still missing or can't get activated. I can't login into web app with errors in logs like "failed to create a control from assembly" like NewsGator and OfficeWebApps. Seems like it's not the way how they should be installed, yet I don't have much options since.. well.. keys are gone.
So my question is how can I transfer all this Features and Solutions to new server so it won't brake, and make it preferably in bulk?
