Review your Setup

Before initiating the migration, it's crucial to assess your existing setup. Take stock of your current Terraform Cloud environment, including the number and complexity of your workspaces, variables, state files, and associated resources. Understanding your current configuration will help you plan and execute the migration more effectively. Read more: Review your setup.

Review your DevOps Process

Evaluate your existing DevOps process to identify any pain points or areas for improvement. Consider factors such as collaboration, version control, infrastructure provisioning, and deployment. This analysis will help you identify key requirements for your new tool, ensuring a better fit for your team's workflows and objectives. Read more: Review your DevOps Process

Prepare the Migration

A successful migration requires careful planning and preparation. Start by creating a detailed migration plan that outlines the tasks, timelines, and responsibilities involved. Identify potential risks and mitigation strategies, ensuring you have a fallback plan in case of any unforeseen issues. Communicate the migration plan with all relevant stakeholders to manage expectations and gain their support. Read more: [Coming soon]

Set up env0

With your migration plan in place, it's time to set up env0 as your new infrastructure-as-code (IaC) tool. Begin by signing up for an env0 account and familiarizing yourself with its features and capabilities. Configure necessary integrations with your version control system (e.g., GitHub) and any other tools that your team relies on for automation, testing, or deployment.

env0 offers an intuitive user interface, fine-grained access controls, and collaborative features to simplify infrastructure management. Spend time understanding and customizing these settings to align with your organization's requirements. Read more: [Coming soon]

Migrate the Workspaces

The most critical aspect of the migration is moving your existing Terraform workspaces to env0. Follow these steps to ensure a smooth transition:

a. Export Terraform Configurations: Extract the Terraform configurations from your Terraform Cloud workspaces such as git repo, branch, and variables. This can typically be done by using TFC’s api.

b. Set up Workspaces in env0: Create equivalent workspaces in env0, ensuring that the necessary environment variables, input variables, and backend configurations are replicated accurately.

c. Version Control Integration: Connect your env0 workspaces with your preferred version control system. This allows seamless synchronization between your codebase and env0, ensuring consistency and easy collaboration.

d. Migrate State Files: Depending on the location of your current state, and the env0 features you want to take advantage of (like Remote Plan), you may need to migrate the Terraform state files to env0. This ensures that env0 has the latest information about your infrastructure resources.

e. Testing and Validation: Before executing any deployments, thoroughly test and validate your migrated workspaces in env0. Run plan operations to detect any potential issues or conflicts and resolve them accordingly.

f. Go Live: Once you are confident in the accuracy and functionality of your migrated workspaces, it's time to switch over to env0 for your infrastructure provisioning and deployment. Communicate the transition to your team members and stakeholders, ensuring they are aware of the changes and have access to the new tool.
