How to reboot Stargate without erasing its fleet

What should a proper Stargate reboot look like, and how much gate technology should it retain?

Prefer a next-generation continuation that keeps the accumulated technology, treats BC-304s as aging ships, and uses former characters as senior advisers.

Two approaches are considered: restarting the story from the beginning or continuing with a new generation after SG-1, Atlantis, and Universe. Jack O'Neill's clone is suggested as one possible link to the earlier story. A later setting would let new crews inherit accumulated gate technology while treating BC-304s as ageing ships needing successors. Returning actors could appear as advisers without taking over the new characters' work. The preference for continuity is tempered by disagreement about whether a new production would be handled well.
