WordPress to Azure Migration

If your WordPress site has outgrown shared hosting or a managed WordPress platform, migrating to Microsoft Azure provides enterprise-grade infrastructure, deep integration with the Microsoft ecosystem, and the scalability to handle any traffic level. Azure's global network of data centres, managed database services, and integrated CDN make it an excellent home for WordPress — especially for organisations already using Microsoft 365, Active Directory, or Dynamics. At SoniNow, we deliver seamless WordPress migrations to Azure, ensuring your site is faster, more secure, and more reliable than ever.

Assessment and Planning

A successful migration begins with a complete understanding of your current WordPress environment. We leave no stone unturned.

Environment Audit

Our assessment covers your web server configuration (Apache vs. Nginx, PHP version, php.ini settings), database engine and size (MySQL or MariaDB table counts, storage engine usage, slow queries), media library volume and storage location, active plugins and themes (including version numbers and licence status), and any custom code, child themes, or third-party API integrations. We also document your current hosting plan's resource limits — CPU cores, RAM, concurrent connection limits, and disk IOPS — so we can show exactly how Azure eliminates each limitation.

Compatibility Review

Azure runs WordPress on Linux and Windows VMs, as well as on Azure App Service (Linux). We review your plugin and theme stack for compatibility with the target Azure environment. For example, plugins that depend on Apache .htaccess files need special configuration when migrating to Azure App Service or Nginx-based VMs. We also check for PHP extensions required by your active plugins (e.g., imagick, gd, zip, xmlrpc) and ensure they are enabled.

Migration Plan

Based on the audit, we present a detailed migration plan with a timeline, risk assessment, and rollback strategy. We define the migration window (lowest traffic period for your audience), the expected downtime (typically under 15 minutes for the final cutover), and the validation checklist that must pass before DNS is switched.

Migration Process

Database Migration

We export your WordPress database using mysqldump with best-practice flags (--opt, --single-transaction, --skip-lock-tables). The dump is transferred over an encrypted SSH tunnel to the target Azure Database for MySQL Flexible Server. We import the database and immediately run URL replacements using WP-CLI's search-replace command. For databases larger than 2 GB, we use chunked import with pv for progress monitoring. Azure Database for MySQL offers automatic backups with 35-day retention, read replicas, and burstable compute tiers that save costs during low-traffic periods.

File Migration and Azure Storage

WordPress content — wp-content/uploads, plugins, themes, and any custom directories — is transferred to Azure Blob Storage using azcopy for parallel uploads. We then deploy the Azure Storage for WordPress plugin to serve media files directly from Blob Storage, optionally enabled with Azure CDN (Verizon or Akamai profiles) for global edge caching. This architecture offloads storage from the VM and reduces page load times significantly.

Application Deployment

We deploy WordPress on Azure Virtual Machines (Ubuntu or Debian with LEMP stack) or Azure App Service for Linux Containers for a fully managed experience. Azure App Service handles OS patching, SSL termination, and auto-scaling. For the VM approach, we use cloud-init scripts to provision Nginx, PHP-FPM, and Redis in a repeatable, infrastructure-as-code fashion.

DNS Cutover

After staging validation — every page loads, all forms submit, WooCommerce transactions process — we cut over DNS. We recommend a 60-second TTL for the migration day, point the custom domain to Azure Front Door or the App Service endpoint, and enable Azure CDN for static assets. We monitor for DNS propagation and error rates for 48 hours post-migration.

Performance Optimisation

Caching Stack

We implement a layered caching architecture specific to Azure:

• Redis cache via Azure Cache for Redis — object caching for WordPress database queries and fragments
• Page caching — Nginx FastCGI cache or App Service local cache for anonymous visitors
• CDN caching — Azure CDN from Verizon profile with rules engine for fine-grained caching behaviour

Database Tuning

Azure Database for MySQL Flexible Server is configured with your workload's requirements — innodb_buffer_pool_size, connection pooling via ProxySQL if needed, slow query logging with long_query_time set to 1 second, and automated index usage analysis. For high-traffic sites, we enable read replicas in the same region to offload reporting and search queries.

Image Optimisation

Beyond serving from Azure CDN, we configure automatic WebP conversion and lazy loading. Azure Functions can be triggered on new uploads to compress images serverlessly, keeping the pipeline efficient and hands-off.

Security Hardening

Azure Security Centre

Microsoft Defender for Cloud continuously assesses your WordPress environment against best-practice recommendations and regulatory compliance frameworks. We configure just-in-time VM access (JIT), adaptive application controls, and file integrity monitoring.

Network Security

The WordPress VM or App Service sits behind Azure Front Door or Application Gateway with WAF policies that block SQL injection, XSS, and OWASP Top 10 threats. Network Security Groups (NSGs) restrict inbound traffic to only Front Door's IP ranges. Azure Bastion provides secure RDP/SSH access without public IP exposure.

Identity and Access

Azure AD integration enables SSO for the WordPress admin panel using the Azure AD SSO plugin. This allows your team to log in with their Microsoft work accounts, with conditional access policies enforcing MFA for administrative access.

Backups and Disaster Recovery

We configure Azure Backup for daily VM-consistent snapshots with a 30-day retention policy, and Azure Site Recovery for replication to a paired region. Database backups are handled natively by Azure Database for MySQL with geo-redundant storage.

Cost Optimisation

Azure provides multiple levers to control WordPress hosting costs. We right-size VMs based on actual CPU/memory data from your current host, recommend Reserved Instances or Azure Savings Plans for predictable workloads (saving up to 72%), and use Azure Hybrid Benefit if you have existing Windows Server or SQL Server licences. Blob Storage lifecycle policies archive infrequently accessed media to the Cool or Archive tier.
