+# Updating mobile provisioning profile CIPD package
+
+Once per year, the iOS development signing certificate used by devicelab and
+chrome bots expires and a new one must be issued. Once the new certificate has
+been created, a new provisioning profile needs to be created that will allow
+apps signed with both the old and new certificate to run on physical test
+devices.
+
+These instructions cover one sub-step of the process of renewing our DeviceLab
+development signing certificates. For the full set of instructions, which are
+Google-internal, see
+[How to renew the DeviceLab development certificate][renew_dev_cert].
+
+[renew_dev_cert]: https://g3doc.corp.google.com/company/teams/flutter/infrastructure/devicelab/apple_cert_renewal.md
+
+
+## Steps
+
+1. Request write access via http://go/flutter-luci-cipd#requesting-write-read-access-to-cipd-packages.
+
+2. Wait about 5 minutes for access rights to sync.
+
+3. Copy the updated iOS provisioning profile to a file named `development.mobileprovision` in this directory.
+
+4. Run `cipd create --pkg-def mac-arm64.yaml`.
+
+5. Verify the package has been uploaded at: https://chrome-infra-packages.appspot.com/p/flutter_internal/mac/mobileprovision/mac-arm64
+
+6. Click on the latest upload and copy the `Instance_ID` value.
+
+7. Run `cipd create --pkg-def mac-amd64.yaml`.
+
+8. Verify the package has been uploaded at: https://chrome-infra-packages.appspot.com/p/flutter_internal/mac/mobileprovision/mac-amd64
+
+9. Click on the latest upload and copy the `Instance_ID` value.
+
+10. Set the `latest` ref to the latest arm64 upload via the following command, replacing with the instance ID copied above:
+
+   ```sh
+   cipd set-ref flutter_internal/mac/mobileprovision/mac-arm64 -ref latest -version ARM64_INSTANCE_ID
+   ```
+
+11. Set the `latest` ref to the latest amd64 upload via the following command, replacing with the instance ID copied above:
+
+   ```sh
+   cipd set-ref flutter_internal/mac/mobileprovision/mac-amd64 -ref latest -version AMD64_INSTANCE_ID
+   ```
+
+12. Set the `version:to_2025` (or appropriate year) tag on the latest arm64 upload via the following command:
+
+   ```sh
+   cipd set-tag flutter_internal/mac/mobileprovision/mac-arm64 -tag "version:to_2025" -version ARM64_INSTANCE_ID
+   ```
+
+13. Set the `version:to_2025` (or appropriate year) tag on the latest amd64 upload via the following command:
+
+   ```sh
+   cipd set-tag flutter_internal/mac/mobileprovision/mac-amd64 -tag "version:to_2025" -version AMD64_INSTANCE_ID
+   ```
+
+14. Update `.ci.yaml` and migrate `apple_signing` steps to the new version tag.  
+    Before: `{"dependency": "apple_signing", "version": "version:to_2024"}`  
+    After: `{"dependency": "apple_signing", "version": "version:to_2025"}`
