From your existing config/s3 repo setup. Download the state with following command.
- terraform state pull > terraform.tfstate
- aws s3 cp –sse AES256 terraform.tfstate s3://Bucket_Name/Whatever_Path/terraform.tfstate
- Updated your backend config with new s3 location and change the profile for that account in your terrafrom config or backend config.
- Run terrafrom init
It will throw an error such as
Error loading state: state data in S3 does not have the expected content. This may be caused by unusually long delays in S3 processing a previous state update. Please wait for a minute or two and try again. If this problem persists, and neither S3 nor DynamoDB are experiencing an outage, you may need to manually verify the remote state and update the Digest value stored in the DynamoDB table to the following value: fe1212121Blah_Blah_Blah_1mduynend Terraform failed to load the default state from the "s3" backend. State migration cannot occur unless the state can be loaded. Backend modification and state migration has been aborted. The state in both the source and the destination remain unmodified. Please resolve the above error and try again.
4. Go to your dynamoDB table config that you have setup in your AWS console for the table and LockID string. Search for the KEY that you have provided for LockID and change the value there with above mentioned fe1212121Blah_Blah_Blah_1mduynend value in last error.
5. Run terraform init again
This should move your S3 state from one bucket to new account’s bucket.
