 ## Limitations
 
-**Use Azure Cosmos DB for NoSQL to store threads**  
+There are some limitations you should be aware of when you plan to use existing resources wtih the Azure AI Foundry Agent Service
+
+### If previously were using a hub-based project or Azure OpenAI Assistants
+
+At this time, there is no direct upgrade path to migrate existing agents or their associated data assets such as files, threads, or vector stores from a hub-based project to an Azure AI Foundry project. There is also no upgrade path to convert existing Azure OpenAI Assistants into Foundry Agents, nor a way to automatically migrate Assistants' files, threads, or vector stores.
+
+You can reuse your existing model deployments and quota from Azure AI Services or Azure OpenAI resources within a Foundry project.
+
+If you want to create a [basic agent setup](#choose-basic-or-standard-agent-setup), you can create a new project in the Azure AI Foundry by selecting **AI Foundry** > **Create new**, or using the bicep template later in this article.

+
+If you want to create a [standard agent setup](#choose-basic-or-standard-agent-setup), setup steps are described later in this article. 
+
+### SDK usage with hub-based projects
+
+Starting in May 2025, the Azure AI Agent Service uses an endpoint for [Foundry projects](../../what-is-azure-ai-foundry.md#project-types) instead of the connection string that were used for hub-based projects before this time. Connection strings are no longer supported in current versions of the SDKs and REST API. We recommend creating a new foundry project.
+
+If you want to continue using your hub-based project and connection string, you will need to: 
+* Use the connection string for your project located under **Connection string** in the overview of your project. 
+
+    :::image type="content" source="../../media/quickstarts/azure-ai-sdk/connection-string.png" alt-text="A screenshot showing the legacy connection string for a hub-based project.":::
+
+* Use one of the previous versions of the SDK and the associated sample code:
+    * [C#](https://github.com/Azure/azure-sdk-for-net/tree/feature/azure-ai-agents/sdk/ai/Azure.AI.Projects/samples): `1.0.0-beta.2` or earlier
+    * [Python](https://github.com/Azure/azure-sdk-for-python/tree/feature/azure-ai-projects-beta10/sdk/ai/azure-ai-projects/samples/agents): `1.0.0b10` or earlier
+
+
+
+
+### Azure Cosmos DB for NoSQL to store threads 
+
 - Your existing Azure Cosmos DB for NoSQL account used in a [standard setup](#choose-basic-or-standard-agent-setup) must have a total throughput limit of at least 3000 RU/s. Both provisioned throughput and serverless are supported.
 - Three containers will be provisioned in your existing Cosmos DB account, each requiring 1000 RU/s
