Updating PCB in number of Layers and PCB Merging

[robertferanec]

I would add the two new layers into the middle of the stackup. Then, you still could use most from the 4 layer layout and simply add everything new on the two new layers.

4 - Layer stack-up - Signal(T) - GND(layer) - Split power plane - Signal(B).
6 - Layer stack-up - Signal(T) - Split power plane - Signal - Signal - GND(layer) - Signal(B).
I may use one of the 2 new signal layers for drawing power polygons, and on other, I may route few signals. Actually, I am planning to merge this 4 layer PCB with a 6 layer PCB. When I had gone through this article - "http://www.fedevel.com/designhelp/forum/main-forum/altium/4130-pcb-merge" I came to know that the two individual PCBs should be same in a number of layers, names, and stack-up. This is why as a first step I am updating this to 6-layer PCB. So, I may not use those two new layers much.

I think I have answered your question!

How are you planning to use the 2 new layers?

Hello everyone ,

I want to update my design from 4-layer PCB to 6-layer PCB, please find the two stack-ups(4-layer and 6-layer) below. Could anyone suggest me the best way of doing it, so that it reduces putting more effort in doing changes?

Thanks in advance.
