A working example could use Diverse Optics of Tancredi IV.
Here's the scene:
So the First Succession War starts in earnest, a Prince John Davion frantically moves to protect his high-tech laser industry. He authorizes the complete redistribution of Diverse Optics's operation from Tancredi IV to Numenor - a suitable A+ planet deep within the Federated Suns.
The AFFS then moves the factory, the computer cores, the foundries, the mills, the lens factories, and all of the other component manufacturers, plus Diverse's technicians and engineers to a safe haven. They conduct the operation quickly with extra DropShips and JumpShips, and technicians familiar with the maintenance and use of advanced laser systems.
Pull it off and victory goes to House Davion. The Combine never comes closer to New Avalon than its ill-fated first invasion and Numenor remains a shining beacon of high tech industry. So high tech in fact, that the other Successor States bow to the inevitable. They are simply outmatched by Davion technology after two devastating wars.
However, lose one of the above mentioned components of Diverse Optics and lack a replacement, and Diverse is either building less sophisticated lasers or none at all.
This is basically what happened to most production firms after the first two Succession Wars. Assuming their equipment survived the ravages of time and poor maintenance, and there was a less sophisticated product to fall back on. Not every factory was bombed into a useless husk. Plenty just fell into disuse because there was no other alternative to their original function. Scavenged for parts for use elsewhere was a typical fate for these manufacturing "war orphans".
A good example is the Industrial Mech industry. What survived actual combat was cannibalized to support the remaining war factories.
Worse still, what if the Combine gets wind of the operation? What if they catch the operation mid-stride? The AFFS could be out Diverse Optics, a load of well trained technicians (technicians pulled from combat commands that could use their skills), and maybe a fleet of irreplaceable JumpShips & DropShips.
That's a lot to risk.
Just something to think about...
