It really depends on your investment philosophy, but I'd keep the same assuming you are fairly young.
Your investment horizon is 50 years. The fact that you are retired now shouldn't change that fact, that you need your money to last that long (or more, or less, or whatever). You may want to get more conservative as you age, but not just because you're retired versus not, IMO.
It'd be dangerous to make a more conservative AA just because you ER'd at 35, then have your money run out at 60 (or, more likely, have the buying power so eroded due to inflation, because you went with a more conservative AA that didn't keep up with or outpace inflation).
