Pre-generate SSL certs, now in the Domains dashboard
By Steven Van ·
Vercel's Domains dashboard can now issue certificates ahead of DNS changes, so domain migrations happen with zero downtime.
Vercel's Domains dashboard can now pre-generate SSL certificates for a domain being migrated to the platform, without using the CLI. After adding an existing domain to a project, selecting Pre-Generate Certificate issues the certificate before DNS records are updated, allowing the rest of the migration to happen with zero downtime. The option only appears if no certificate has already been issued for that domain. Importing a zone file or using Domain Connect to migrate DNS records from a previous provider is still supported.
