Ideally, the lower headset bearing race (or fork crown race) to axle length and the fork rake (or offset) would match the old fork if you want the handling to be the same.
I am not a frame designer, so I can't elaborate on how handling changes as you deviate from the original fork measurements.
Example, several years ago I bought a new frame from the manufacturer without the fork. The manufacturer recommended fork length from the crown race to axle and the fork rake were nearly identical to an old rim brake fork that I had in storage, so I used my old fork instead of buying the disc brake fork that the frame manufacturer suggested, saving over $400. I was happy to save the money, the result is a bike with rim brake front and disc brake rear, which works just fine.
