# MIGRATIONS-FLAGS:
|

# SKIP_CLIENT_DNS=true → Abschnitt 8 (imap/smtp/pop/webmail) + 10 (SRV) überspringen
|

# Nutzen: Client-Subdomains bleiben beim alten Provider

# SKIP_DMARC=true → Abschnitt 7 (DMARC) überspringen

# Phase 0 (Vorbereitung): SKIP_CLIENT_DNS=true SKIP_DMARC=true → nur SES + SPF
|

# Phase 1 (MX Cutover): MX umstellen (manuell)

# Phase 2 (Client Switch): ohne SKIP Flags → alle Records setzen
