Rebalance ETFs or sell all and buy new ETF?

I've been in the market for about 10 years and my portfolio consists of VUN, VCN, VDU and VEE.

I need to rebalance my portfolio, but I was thinking maybe I should just sell it all and buy an all in one ETF like VEQT or VBAL. Those ETFs look to be made up of the ones I own anyways.

Wouldn't cost me much to make all the trades. Just not sure if that's the right way to go.

Any thoughts/feedback would be great. I still have about 15 years until retirement and won't need this money right away.
