Di2 10 speed questions
I was curious if all shimano Di2 10 speed components are interchangeable?
For example, if I had a bike with Di2 ultegra, can I switch out any part to dura ace as long as it is 10 speed? shifters, derailleurs, etc? Just plug and play right?

nope
6770 uses e-tube. older 7970 uses an entirely different interface. not compatible. 6770 derailleurs are compatible with any other e-tube based shifters though (e.g. 9150 shifters), as long as both derailleurs are 6770 6770 shifters are compatible with any e-tube based derailleurs, as long as both derailleurs are of the same speed

I have the 2.5.2 firmware file that allows 6770 (10s Ultegra) front derailleurs to interface with 6870/9070 (11s Ultegra/DA) rear derailleurs. It will not work with the latest generation of rear derailleurs (Ult8050/DA9150) as they did not exist when the 2.5.2 firmware was published.
This guy has put the firmware out on Dropbox. ETube 2.5.2 Firmware Instructions for the "downgrade" are here: Di2 Firmware Downgrade
