Why Upgrading from Shared Hosting to Managed Cloud is Crucial
Shared hosting accounts frequently throttle CPU cores, impose restrictive PHP memory limits (128M), and suffer from “noisy neighbour” syndrome where another site on the same physical server consumes all I/O. Moving your WordPress site to Cloudways or a dedicated VPS provides isolated RAM, dedicated NVMe disks, and blazing-fast PHP execution.
Step 1: Lower Your DNS TTL Ahead of Time
48 hours before starting your migration, log in to your DNS manager (e.g. Cloudflare, Namecheap, GoDaddy) and reduce the Time To Live (TTL) on your root @ and www records from 14400 (4 hours) to 300 seconds (5 minutes). This guarantees that when you update your server IP, the change propagates worldwide in minutes rather than days.
Step 2: Deploy Cloudways WordPress Migrator Plugin
Cloudways provides an automated migration plugin powered by BlogVault:
- Install and activate the Cloudways WordPress Migrator plugin on your existing site.
- Enter your destination Cloudways server details: Server IP, Database Name, SFTP Username, and Password.
- Click Migrate. The plugin packages files and database tables in chunks without triggering timeout errors.
Step 3: Test on Staging / Hosts File Before Flipping DNS
Never change DNS blindly without testing. Use the Cloudways staging URL or edit your local computer’s hosts file to point your live domain to the new VPS IP. Verify user logins, WooCommerce checkout, and contact forms.
Step 4: Update A Records & Verify SSL
Once tested, point your DNS A record to your new VPS IP. Generate a free Let’s Encrypt SSL certificate via your VPS control panel, and enjoy instant 2x to 5x faster page response times.

Post-Migration DNS Switching & Varnish Cache Tuning
Once your WordPress files and database have populated your Cloudways application, the final step is executing a zero-downtime DNS switch. Point your domain’s A Record to your new Cloudways server IP address while keeping the old hosting environment active for 24 hours to capture lingering requests from lagging ISPs.
Cloudways deploys a multi-tier caching stack comprising Varnish HTTP accelerator, Nginx reverse proxy, and Apache. To prevent layout corruption and stale admin views, configure the official Cloudways Breeze plugin to automatically flush Varnish whenever posts or products are updated.
