A properly executed HubSpot migration causes zero downtime for visitors. Your current website stays live throughout the entire migration process. The new HubSpot site is built and tested in a staging environment, and the cutover happens through a DNS switch that routes traffic to the new site once it is fully ready. The staging environment is where all template development, content recreation, and quality assurance happen. Visitors to your live site see no changes until the DNS switch occurs. The DNS cutover itself involves updating your domain's nameserver records to point to HubSpot's servers. DNS propagation (the time it takes for the change to spread across internet providers) typically completes within a few hours, though it can take up to 48 hours for all global DNS servers to update. During propagation, some visitors may see the old site while others see the new one. This is normal and does not create a "down" period. SSL certificate provisioning on HubSpot's side usually completes within minutes of the DNS switch. To minimize any perception of disruption, most teams schedule the DNS cutover during low-traffic hours, typically evenings or weekends. ### Ask AI about Lean Labs [
