+# Fase 2: CWP Migration (Week 3-6)
+
+Target: Migrar 39 vhosts CWP para VM AlmaLinux 8
+
+**CRITICAL:** 7 dias safety net - server.descomplicar.pt intacto
+
+## 2.1 Criar VM AlmaLinux 8 + CWP
+
+```bash
+qm create 300 \
+  --name cwp-legacy \
+  --memory 16384 \
+  --cores 6 \
+  --net0 virtio,bridge=vmbr0 \
+  --scsi0 rpool/vm-disks:150 \
+  --ostype l26
+
+# Instalar AlmaLinux 8
+# Instalar CWP7
+wget http://centos-webpanel.com/cwp-el8-latest
+sh cwp-el8-latest
+```
+
+## 2.2 Backup CWP Accounts
+
+```bash
+# Em server.descomplicar.pt
+for account in $(cat /tmp/cwp-accounts.txt); do
+  /scripts/pkgacct $account
+done
+
+# Transfer backups
+rsync -avz /home/backup-*/cpmove-*.tar.gz \
+  root@cluster.descomplicar.pt:/mnt/migration/cwp/
+```
+
+## 2.3 Migrar Contas (Batch 3-5 contas)
+
+Workflow por conta:
+
+```bash
+# 1. Restore backup em VM CWP
+scp /mnt/migration/cwp/cpmove-ACCOUNT.tar.gz root@10.10.10.300:/home/
+
+# 2. Restore via CWP
+/scripts/restorepkg ACCOUNT
+
+# 3. Validar:
+- Site carrega (HTTP 200)
+- Database conecta
+- Email funciona (send test)
+- SSL certificado valido
+
+# 4. DNS cutover (TTL 300s)
+A record: site.com -> 10.10.10.300 (via NAT port forward)
+
+# 5. Monitorizar 24h
+```
+
+## 2.4 Validation Period (7 dias)
+
+```bash
+# Days 1-7 apos migration:
+- Server antigo (server.descomplicar.pt) INTACTO
+- Rollback instantaneo se problema critical
+- Cliente pode reverter DNS manualmente se necessario
+
+# Day 7: Confirmar com Emanuel
+# Se tudo OK -> proceder cleanup
+# Se problemas -> extend validation ou rollback completo
+```
+
+## 2.5 Email Migration
+
+```bash
+# Por cada conta CWP:
+
+# 1. Backup mailboxes
+tar -czf /tmp/mail-ACCOUNT.tar.gz /home/ACCOUNT/mail/
+
+# 2. Transfer
+scp /tmp/mail-ACCOUNT.tar.gz root@10.10.10.300:/tmp/
+
+# 3. Restore
+cd /home/ACCOUNT/
+tar -xzf /tmp/mail-ACCOUNT.tar.gz
+
+# 4. Fix permissions
+chown -R ACCOUNT:ACCOUNT /home/ACCOUNT/mail/
+
+# 5. Testar IMAP/SMTP
+telnet localhost 143  # IMAP
+telnet localhost 25   # SMTP
+```
+
+## 2.6 Rollback Procedure (Fase 2)
+
+```bash
+# Disponivel ate Day 7
+
+# 1. Reverter DNS (todos sites)
+A records -> IP antigo (server.descomplicar.pt)
+
+# 2. Verificar server antigo online
+ping server.descomplicar.pt
+
+# 3. Comunicar clientes
+
+# 4. Analisar causa falha
+
+# 5. Ajustar plan e re-tentar
+```
