Zero Downtime Game Server Migration: A Safe Cutover Plan
Move to a new host without losing players with staged sync and short maintenance windows.
A safe migration keeps players online while you move infrastructure.
Sync configs and world data ahead of time. Keep the old server running during the sync.
Lower DNS TTL, announce a small maintenance window, then switch traffic.
Test join and queries, then keep the old server available for a quick rollback.
A calm migration is a planned migration.
