3 way and 4 way replacement switch question.

[Junkman]

I would like to replace all the 35 year old toggle switches in the home with the newer paddle type of switches. My question concerns the wiring of the switches. Can I assume that the terminal locations on the old switches is going to be the same as the terminal locations on the new switches? When I wired the home 35 years ago, I had help with the 3 & 4 way switches, so I never learned exactly how they work. I don't want to get into this, only to find that I messed up something, and have to spend hours trying to fix what should have been a 1/2 or 1 hour job.
Thanks Junk

On the 3 ways just make sure to put put the same wire to the common/black screw,you'll be fine.

On 4 ways just make sure to use the same pairs on the top and bottom.
You can swith them from top to bottom,just make sure they're paired the same is all.
