When your configuration includes a cloud block, commands that
make local modifications to OpenTofu state and then push them back up to the remote workspace
accept the following option to modify that behavior:
-ignore-remote-version - Override checking that the local and remote
OpenTofu versions agree, making an operation proceed even when there is
a mismatch.
State-modification operations usually require using a local version of the OpenTofu CLI that is compatible with the OpenTofu version selected in the remote workspace settings. This prevents the local operation from creating a new state snapshot that the workspace's remote execution environment cannot decode.
We recommend against using this option unless absolutely necessary. Overriding this check can result in a cloud backend workspace that is no longer able to complete remote operations with the currently selected version of OpenTofu.
