Fadaie's own domain checklist

Before changing the permanent Fadaie website, document its registrar, registrant organization, recovery email and phone, expiration date, auto-renew status, billing owner, nameservers, DNS provider, DNSSEC status, and named administrators. Use individual accounts with two-step verification and stored backup codes.

Main-domain cutover

Only after launch approval: confirm the exact production host, finish the WordPress redirect map, preserve analytics and Search Console, protect email records, lower the relevant TTL, test backups and rollback, switch apex/www, verify critical journeys, monitor seven clean days, continue 30-day SEO monitoring, and retain a private WordPress archive for 60–90 days before decommissioning.
