Before migrating, the wizard checks your selected workspaces for issues that need resolution. It tells you exactly what needs attention. If no issues are found, you skip directly to review.
Issue types
Missing secrets
TFC marks sensitive variables as write-only, so their values cannot be read during the scan. You need to re-enter these values before migration.
Missing secrets can appear in two places:
- Workspace variables - sensitive variables defined on individual workspaces
- Variable set variables - sensitive variables defined in variable sets shared across workspaces
For each item with missing secrets, the wizard displays a card showing the variable names that need values.
Click on a workspace or variable set card
The card expands to show all sensitive variables that need values.
Enter the secret values
Provide the current value for each sensitive variable. You can also mark a variable as skipped if it is no longer needed.
Save
The card updates to reflect the resolved status.
VCS connection required
Some workspaces reference VCS repositories through providers that are not yet connected in env zero. The wizard lists these and prompts you to configure the VCS connection in env zero before proceeding.
Workspaces with unsupported VCS providers (providers not supported by env zero) are automatically excluded from migration.
No issues found
If all selected workspaces pass validation, the wizard displays a success message and you can proceed directly to the next step.
Next step
Once all issues are resolved or skipped, click Next to continue to Review and Migrate.
