Bases have typically been moved in the past when subject to system development changes. For example, Iejima Station was built as a helium-3 ore base in Okinawa, but the developers moved the field to Sigma-19. Iejima was then moved accordingly, free of charge. The same happened when the mining field moved from Sigma-19 to Sigma-59.
My feedback would be that bases being moved for the same reason - system changes outside of the owner's control - should still be made without charge.
