OFFICIAL Facility Chains

[smilie224]

I was considering doing a redesign of facilities to different farms. I have several chains set up. If I move a chain facility (such as facility currently on 4 and part of an active chain) to farm 20, do I lose the chain? Or would it pop back up and understand the new farm once I add the facility on F20?

Since the chains take so long to build up, I'd hate to lose all the ones I have just by doing a redesign.

In case it makes more sense writing in this way: Chain set up with airline supplies farms 1 and 2. I want to move the airline supplies facility to farms 40 and 41.
When I remove the airline supplies from farms 1 and 2, do I lose the chain altogether?

Also, I am assuming that I need to buy the airline supplies to place on Farms 40 and 41 before I delete the facilities on Farms 1 and 2?

Thank you for any insights!
