Migration of a legacy website to a modern CMS like WordPress

Migration of legacy websites to other modern CMS is important for improving the website’s security and user experience and enhancing its performance. In this case we are migrating a .NET website to WordPress. Migrating a .NET website to WordPress involves a comprehensive process, from setting up WordPress to transferring content and users. This detailed guide includes steps for key tasks along the way.

Step 1: Setup a WordPress Environment

  1. Choose a Hosting Provider: Select a provider that supports WordPress, many of which offer one-click installation.
  2. Install WordPress: Either use the one-click install option provided by your host or download WordPress from wordpress.org and follow the famous 5-minute installation guide.

Step 2: Theme Selection and Setup

  1. Choose a Theme: Pick a theme that aligns with the aesthetic of your .NET site or opt for a custom theme for a more tailored look.
  2. Install Your Theme: Navigate to Appearance > Themes > Add New in your WordPress dashboard, upload the theme, and activate it.

Step 3: Content Migration

Content migration varies widely based on your specific .NET setup, but a common approach involves exporting data to a universal format like CSV or XML, then importing it into WordPress.

  1. Export Content from .NET Website: The method depends on your .NET site's architecture. For sites using a CMS, export tools might be available. For custom solutions, you may need to export your database content to CSV or XML.
  2. SQL Server Export to CSV Example:
  1. Use SQL Server Management Studio (SSMS) or similar to run this query and export the results.
  2. Convert Content Format (if necessary): WordPress typically imports data in WXR (WordPress eXtended RSS), so converting your exported data to WXR or another compatible format might be required.
  3. Import Content into WordPress: Use the WordPress Importer for XML/WXR files or plugins like WP All Import for CSV files. These tools allow you to map your data to WordPress fields.

Step 4: Migrating Users

  1. Export Users from .NET: Extract user data into a CSV, including essential information like usernames, email addresses, and hashed passwords.
  2. Import Users into WordPress: Utilize plugins such as Import users from CSV with meta. Note that you might need to address password compatibility or reset issues.

Step 6: Testing and Optimization

  1. Test the Site: Ensure all content is correctly migrated, check for broken links, and verify user logins.
  2. Optimize: Use caching plugins, optimize images, and analyze site performance with tools like Google PageSpeed Insights.

Step 7: Go Live

  1. Update DNS Settings: Point your domain to the new WordPress hosting environment.
  2. Monitor the Site: Keep an eye out for any issues post-launch and be ready to fix them.

Final Notes

  • Custom Functionality: For features unique to your .NET site, search for WordPress plugins or consider developing custom plugins.
  • Manual Work: Certain aspects, especially those related to design and bespoke functionality, may require manual intervention.
