Cadstar Help - how to merge two different designs into one P

[minus3db]

Hi all, I am really hoping that a Cadstar guru out there can help me
with this problem.

I have two different schematics, each with their own unique PCB. I
want to combine the two existing PCB layouts into a single new PCB
layout.

Here's the problem: there are common component designators between both
schematics. For example, there is a diode D1 in schematic/PCB #1, and
a diode D1 also in schematic/PCB #2.
This is the case for several hundred component designators on both
boards.

I've tried to combine the two schematics together, which changes the
component designators for schematic #2. As a result, when I try to
stitch the two PCB layouts together, I'm unable to generate an ECO
update, since the component designators no longer match.

Has anybody had this problem before? I'd appreciate *any* feedback
that might help me solve this problem.

Thanks in advance,
minus3db

Maybe do it with a Gerber editor, just paste them both into a common

file?

But surely he can't keep duplicate references on the final board - how will the
assemblers know which R1 is which?

One would asume that it is two separate PCBs, that is just combined to
make manufacturing cheaper.
