Best practices for managing state files during AWS Terraform migration

I've spent hours debugging this and I recently switched to While migrating an existing application to AWS using Terraform, I’ve been exploring ways to manage state files effectively. The project requires multiple environments for staging and production, and I want to ensure that the state files remain isolated yet accessible. I initially attempted to use the default local backend, but I quickly realized that this led to confusion and version conflicts, especially when collaborating with the team. To tackle this, I set up an S3 bucket to store the state files with the following configuration: ```hcl terraform { backend "s3" { bucket = "my-tf-state-bucket" key = "terraform/state" region = "us-west-2" } } ``` This change allowed us to centralize the state, but I ran into issues with locking. After looking through the documentation, I added DynamoDB for state locking: ```hcl terraform { backend "s3" { bucket = "my-tf-state-bucket" key = "terraform/state" region = "us-west-2" dynamodb_table = "terraform-locks" } } ``` However, I’m still concerned about managing workspaces for different environments. At first, I tried creating separate directories for each environment, but that led to duplicated code and maintenance overhead. I transitioned to using Terraform workspaces, but I still find it challenging to maintain different configurations across environments. Here’s how I’m currently managing that: ```bash tf workspace new staging tf workspace new production ``` What are the best practices for managing state files in Terraform, especially during a migration project? Are there any specific strategies or patterns you recommend to ensure smooth collaboration and environment isolation? I'm open to any suggestions.
