Terraform upgrade causing issues

[sandy-0007]

At present, I am running on Atlantis version="0.17.2" and Terraform="0.13.5".
Later, I upgraded the Atlantis="0.17.5" and Terraform="1.1.1"

When I ran the "atlantis plan", I got to the below error

Error: Backend configuration changed

A change in the backend configuration has been detected, which may require
migrating existing state.

If you wish to attempt automatic migration of the state, use "terraform init
-migrate-state".
If you wish to store the current configuration with no changes to the state,
use "terraform init -reconfigure"

FYI, all my state files are stored in remote cloud bucket. Looking for your kind advice on how I could get this fixed without corrupting the existing state.

You are probably going to want to follow the upgrade guides:
https://www.terraform.io/language/upgrade-guides

If you think your code is ready for the version update, you could add the parameters to your atlantis config:

- init:
    extra_args: ["-migrate-state"]

Just made a new release 0.18.0 (let me know if that fixed your issue, thanks!)
