Checklist for Big Website Migration

Creating a Staging Environment for your Website

Establishing a staging environment for your website is highly recommended before the site migration. A staging environment is a separate, and isolated replica of your live website where you can test and experiment without affecting the actual site that your users see. It allows you to assess the impact of changes, identify any issues or bugs, and make necessary adjustments before deploying them to the live environment. By creating a staging environment, you can ensure the stability and functionality of your website while minimizing the risk of potential downtime or user disruption. It provides a controlled space where you can test new features, plugins, design modifications, or even perform full site migrations without compromising the live site’s performance. 

A staging environment allows collaboration among team members or stakeholders, as they can review and provide feedback on the proposed changes before implementation. Overall, a staging environment is a valuable asset in maintaining the integrity and quality of your website while facilitating safe and efficient development processes.

Mapping all your Valuable Content

It is crucial to dedicate additional effort to identifying all the top-performing content pieces and ensure no gaps during the site migration. These valuable pieces of content should be meticulously documented in a Google Sheet based on their type and highest organic traffic. Any content actively referenced by paid campaigns should also be included in the mapping process. The content could be – web pages, blogs, events, webinars, and more.

While adding a spreadsheet for mapping the valuable content ensure to add the crucial columns such as,

  • Type of the content
  • Current and old URL
  • Staging URL
  • What type of redirect
  • Language version
  • Current organic traffic

During the process of site migration, it is essential to pay close attention to contact forms. Contact forms serve as a vital means of communication between businesses and their customers. Any disruption or malfunction in contact forms during the migration can lead to missed inquiries, potential loss of business opportunities, and frustrated customers. It is crucial to ensure that contact forms are thoroughly tested before and after the migration process to guarantee their proper functionality. 

This includes verifying that form submissions are being received, email notifications are being sent to the appropriate recipients, and any integrations or third-party services associated with the contact forms are working seamlessly. By prioritizing the integrity of contact forms during the site migration, businesses can maintain a smooth and uninterrupted communication channel with their customers, minimizing any negative impact on customer experience and business operations.

Technical Validation with Google Search Console

It is essential to check for any crawl errors, redirect issues, or missing pages that may arise during the migration process.
