How to Rename an AWS S3 Bucket in Terraform – Step by Step

Renaming an AWS S3 bucket in Terraform involves creating a new bucket with the desired name, moving data over to it, making necessary state replacements, and deleting the old bucket. To achieve this, first create a new bucket using AWS CLI or console while replicating the old settings. Then copy all files from the old to the new bucket. Next, remove the old bucket from Terraform state and import the new one in its place. Update the name of the bucket in your Terraform config and ensure there are no changes left to be made. Finally, delete the old bucket after confirming data has been successfully copied over. Using Spacelift can help manage this process more efficiently by running arbitrary AWS CLI commands and locking the Stack during migration.
