All, In My lab environment I'm just playing with Windows 10 In place upgrade..
I have windows 8.1 Enterprise Evaluation version .... On top of that with SCCM Trying to deploy windows 10 Evaluation Version ..Task sequence Failed with 0xC1900204. What exactly it means *Migration choice (auto upgrade) not available (probably the wrong SKU or architecture)· 0xC1900204* So evaluation version it wont support ? Kevin
