Pulumi has introduced the "pulumi state move" command, which facilitates the movement of resources between stacks and projects within the same backend, streamlining the refactoring of Infrastructure as Code (IaC) without affecting deployed cloud infrastructure. This command addresses the previously complex and error-prone process by allowing users to transfer resources, including their relationships, between stacks while preserving dependencies where applicable. It is particularly useful for splitting monolithic projects into micro stacks or merging multiple stacks. The command requires specifying resources by their full URN and enables users to adjust their code accordingly post-move, using stack references or reconfiguring inputs and outputs. Pulumi also offers guidance on using this command effectively through examples and encourages feedback from its community.
