Being as collaborative as you can be is a good start. Outside of that, being honest and transparent about why the changes are happening is a good way to build trust with the new team. Keeping a positive attitude and energy around it will also help to soften the blow. Most importantly, continually ask the new team for their feedback along the way. This will help them to understand that while you are implementing new procedures to help things run "your way," you still respect and value their opinion.
Best of luck!
