How to transition invested down payment from equity ETFs to lower risk/income ETFs/products?

Hi, like the title states, I am planning on buying a house in the next two years. My current investments are in all equity ETFs (VEQT & XEQT). I know this money should be in lower risk/income ETFs/portfolios. I guess I just need the push to move them into those products. Do you generally have a strategy when transitioning investments from high risk to lower risk as you get closer to needing the money for the down payment? Is it gradual or do you do it all at once?
