Very few symbols them selves have been renamed. We mainly moved them 
around to other libs.
I don't know exactly how the remapping would handle that case. But worst 
case you can switch over to the new lib using a kicad 4 release and do 
the remapping after you transferred over to the new lib. (Don't try to 
do both at once. There is just more that can go wrong that way.)

Be careful with libs that have symbols with invisible power pins in 
them. (logic libs) We eliminated these type of symbols and changed them 
to have a separate unit for the power pins. (Sadly ERC will not complain 
if you don't place the power unit down. So if you update to the new 
symbols and forget to manually place the power unit you will get a pcb 
that has ICs in there that are not connected to power.)
