hey guys, anyone have any info on a 6L80e swap into a NBS 07/08 truck?

From what I can gather, I need to flash the ECM with a 6.0/6.2L engine cal, get the trans in and swap the 5.3L/60e engine/trans harness with a 6.2/6l80e harness.
All this to just make it seem like a stock, factory like install.
