There shouldn't be any SCCM specialization in the WinPE.wim - only extra WinPE components like MDAC, Powershell etc . The ConfigMgr specialization happens in the WinPE wim that has the package ID appended to the name of the WIM. So make sure you use the WimPE.wim and not WinPE.XXX2nnnn.wim.
There is also some site specialization done at the time the boot device is created (USB Stick, CD ROM etc) I am using WinPE for ADK 1511 and I didn't want to have to redo the hotfix patch so I just imported the already patched one from my test environment. It works fine to import WinPE.WIM from test to prod.

I have a dev environment that they upgraded correctly. Is it okay to just import the images from that location to production? Thanks.
