Migrating to a VDS gives you root access, dedicated resources, and unlimited sites. Process: backup → transfer files + DB → configure Nginx → test → switch DNS.
rsync -avz user@shared:~/public_html/ root@VDS-IP:/var/www/example.com/
mysqldump -u dbuser -p dbname > backup-db.sql
mysql -u myuser -p mysite < backup-db.sql
Lower your DNS TTL to 300 seconds 24 hours before migration. Test on VDS via
/etc/hosts before switching DNS to achieve zero downtime.
