Project Migration#

Use the Upgrade command in the Silicon Labs Configurator command-line interface (SLC CLI) to migrate a project based on Simplicity Software Development Kit (SDK) 2025.6 or earlier to 2025.12 or later. The upgrade process updates the project to align with changes to the new folder structure in the SDK 2025.12+. Follow these steps to complete the migration.

Note: Running both commands performs an in-place project migration and upgrade.

1. Upgrade the project to the Simplicity SDK 2025.12.

   > slc upgrade -p project.slcp --sdk-package-path <sisdk_2025.12_location>,<extension_location>> slc upgrade -p project.slcp --sdk-package-path <sisdk_2025.12_location>,<extension_location>

2. Regenerate the project files after the upgrade.

   > slc generate -p project.slcp --sdk-package-path <sisdk_2025.12_location>,<extension_location>> slc generate -p project.slcp --sdk-package-path <sisdk_2025.12_location>,<extension_location>
