+## List of model's container upgraded from TGI to VLLM
+1. **codegemma-1.1-2b**
+2. **codegemma-1.1-7b-it**
+3. **codegemma-2b**
+4. **codegemma-7b**
+5. **falcon-40b-instruct**
+6. **gemma-1.1-7b-it**
+7. **gemma-2b**
+8. **gemma-2b-it**
+9. **gemma-7b**
+
+## Impact
+Any model deployment associated with the above models will fail on restart.
+
+## Mitigation 1 - Update the existing registered model 
+If you have registered one of the above models, update the model configuration to use **VLLM** container in place of **TGI** during deployment. To update the registered model and create new deployment on **VLLM** follow the below instructions.
+
+1. Use the **Get Model** Python SDK to get the details for the target model.
+
+```
+# get model
+import oci
+from ads import set_auth
+from oci.auth.signers import get_resource_principals_signer
+from oci.data_science import DataScienceClient
+
+set_auth(auth='resource_principal') 
+
+resource_principal = get_resource_principals_signer() 
+data_science_client = DataScienceClient(config={}, signer=resource_principal)
+
+get_model_response = data_science_client.get_model(
+    model_id="ocid1.datasciencemodel.oc1.iad.amaaaaaay75uckqare76rtyeaghvtsakscn2d6xscrvwyq7f6txc32742m3a")
+
+# Get the data from response
+print(get_model_response.data)
+
+```
+Refer [document](https://docs.oracle.com/en-us/iaas/tools/python-sdk-examples/2.162.0/datascience/get_model.py.html) for more details on get model SDK code.
+
+
+2. Use the response from the **Get Model** call to update the custom_metadata_list within the **Update Model** Python SDK code. Specifically for changing the **deployment-container**, you must:
+
+*  Change the value for the **custom_metadata_list** attribute with the key **deployment-container** to **odsc-vllm-serving**.
+*  Copy all other **custom_metadata_list** attributes (key/value pairs) exactly as they appear in the **Get Model** response, ensuring no existing metadata is accidentally dropped during the update
+
+
+```
+
+import oci
+from ads import set_auth
+from oci.auth.signers import get_resource_principals_signer
+from oci.data_science import DataScienceClient
+
+set_auth(auth='resource_principal') 
+
+resource_principal = get_resource_principals_signer() 
+data_science_client = DataScienceClient(config={}, signer=resource_principal)
+
+# Send the request to service, some parameters are not required, see API
+# doc for more info
+update_model_response = data_science_client.update_model(
+    model_id="ocid1.datasciencemodel.oc1.iad.amaaaaaay75uckqare76rtyeaghvtsakscn2d6xscrvwyq7f6txc32742m3a",
+    update_model_details=oci.data_science.models.UpdateModelDetails(
+        custom_metadata_list=[
+            oci.data_science.models.Metadata(
+                category="Other",
+                description="Deployment container mapping for SMC",
+                key="deployment-container",
+                value="odsc-vllm-serving",
+                has_artifact=False),
+        oci.data_science.models.Metadata(
+                category="Other",
+                description="Fine-tuning container mapping for SMC",
+                key="finetune-container",
+                value="odsc-llm-fine-tuning",
+                has_artifact=False),
+        oci.data_science.models.Metadata(
+                category="Other",
+                description="model by reference flag",
+                key="modelDescription",
+                value="true",
+                has_artifact=False),
+        oci.data_science.models.Metadata(
+                category="Other",
+                description="artifact location",
+                key="artifact_location",
+                value="oci://aqua-test-prod@idtlxnfdweil/custom-models/gemma-2b",
+                has_artifact=False),
+        oci.data_science.models.Metadata(
+                category="Other",
+                description="Evaluation container mapping for SMC",
+                key="evaluation-container",
+                value="odsc-llm-evaluate",
+                has_artifact=False),]))
+
+# Get the data from response
+print(update_model_response.data)
+
+```
+Refer [document](https://docs.oracle.com/en-us/iaas/tools/python-sdk-examples/2.162.0/datascience/update_model.py.html) for more details on update model SDK code.
+
+3. After updating the existing model, wait a short time for the changes to synchronize. Then, create a new model deployment; it will now launch the deployment using the **VLLM** container.
+
+
+
+## Mitigation 2 - Re-register the above models using latest service managed model version 
+
+1. Register the new model which uses the **VLLM** container (Refer to [register model](register-tips.md) document). 
+
+After register the model after the service deprecates **TGI**, the above model will show **VLLM** container instead of **TGI**
