+# Migrate compute management from SDK v1 to v2
+
+The compute management functionally remains unchanged with the v2 development platform.
+
+This article gives a comparison of scenario(s) in SDK v1 and SDK v2.
+
+
+## Create compute instance
+
+* SDK v1
+
+    ```python
+    import datetime
+    import time
+    
+    from azureml.core.compute import ComputeTarget, ComputeInstance
+    from azureml.core.compute_target import ComputeTargetException
+    
+    # Compute Instances need to have a unique name across the region.
+    # Here we create a unique name with current datetime
+    ci_basic_name = "basic-ci" + datetime.datetime.now().strftime("%Y%m%d%H%M")
+    
+    compute_config = ComputeInstance.provisioning_configuration(
+            vm_size='STANDARD_DS3_V2'
+        )
+        instance = ComputeInstance.create(ws, ci_basic_name , compute_config)
+        instance.wait_for_completion(show_output=True)
+    ```
+
+* SDK v2
+
+    ```python
+    # Compute Instances need to have a unique name across the region.
+    # Here we create a unique name with current datetime
+    from azure.ai.ml.entities import ComputeInstance, AmlCompute
+    import datetime
+    
+    ci_basic_name = "basic-ci" + datetime.datetime.now().strftime("%Y%m%d%H%M")
+    ci_basic = ComputeInstance(name=ci_basic_name, size="STANDARD_DS3_v2")
+    ml_client.begin_create_or_update(ci_basic)
+    ```
+
+## Create compute cluster
+
+* SDK v1
+
+    ```python
+    from azureml.core.compute import ComputeTarget, AmlCompute
+    from azureml.core.compute_target import ComputeTargetException
+    
+    # Choose a name for your CPU cluster
+    cpu_cluster_name = "cpucluster"
+    compute_config = AmlCompute.provisioning_configuration(vm_size='STANDARD_DS3_V2',
+                                                               max_nodes=4)
+    cpu_cluster = ComputeTarget.create(ws, cpu_cluster_name, compute_config)
+    cpu_cluster.wait_for_completion(show_output=True)
+    ```
+
+* SDK v2
+
+    ```python
+    from azure.ai.ml.entities import AmlCompute
+    cpu_cluster_name = "cpucluster"
+    cluster_basic = AmlCompute(
+        name=cpu_cluster_name,
+        type="amlcompute",
+        size="STANDARD_DS3_v2",
+        max_instances=4
+    )
+    ml_client.begin_create_or_update(cluster_basic)
+    ```
+
