This is part of a general effort to move all of Terraform's non-library package surface under internal in order to reinforce that these are for internal use within Terraform only. If you were previously importing packages under this prefix into an external codebase, you could pin to an earlier release tag as an interim solution until you've make a plan to achieve the same functionality some other way.

Pull the state from its location, upgrade the local copy, and output it
|
|
to stdout.
|
|
|
|
This command "pulls" the current state and outputs it to stdout.
|
|
As part of this process, Terraform will upgrade the state format of the
|
|
local copy to the current version.
|
|
|
|
The primary use of this is for state stored remotely. This command
|
|
will still work with local state but is less useful for this.
