e38 OS compatibility

[Camaro_68]

Hello, Could someone confirm if these two OS are compatible before I try to download OS 12633056?

e38 ECM Service # 12633238 (should be 2011)

Current ECM OS: 12639835

Want to download OS: 12633056 (I want to upgrade to this OS so I can run a 4l80e with a 2011 L96 engine)

Thanks!

Google this; "e37, e38 e67 OS Compatibility Reference list".
Its from EFILive but it has helped me a few times doing swaps and stuff.
Let me know if it helps, looking at going a LS3 4L60e with a E38 and T42
hope that helps.
