# Upgrading and Migrating FTPS Connector to Version 2.0
Upgrade Anypoint Connector for FTPS (FTPS Connector) to version 2.x.
## Supported Upgrade Paths
From Version | To Version  
---|---  
## Changes in This Release
This release contains the following changes:
  * This connector is now compatible with Java 17.
  * This connector is now FIPS 140-2 compliant.
  * This connector no longer uses reflection to reuse the SSL session from the command channel to data channels. Instead, it now supports SSL session resumption between the client and host by using externally provided Bouncy Castle libraries which are to be set as top security providers. You can add these libraries with the new **Required Libraries** field in the connection type. For more information, refer to Configure Java JDK for Session Reuse and Configure Bouncy Castle Libraries and Security Provider. Because Bouncy Castle security providers are required for running FTPS on Java 17, all Mule applications within the same JVM must adhere to its stricter cryptographic policies. This includes enforcing modern key sizes, secure algorithms, and updated TLS configurations—affecting keystores, truststores, and all TLS-based connectors.
  * The `mule-file-commons` module dependency is removed.
  * The **List** operation now returns the file path instead of the file content.


## Requirements
Ensure that you meet these requirements before you perform the upgrade:
Application/Service | Version  
---|---  
4.3.0 and later  
## Limitations
Before you perform the upgrade, be aware of these known limitations:
  * Session reuse doesn’t work well with TLS 1.3 in CloudHub (same as with previous versions of FTPS Connector).
  * The security providers are hardcoded, which means all Mule applications running on the same Java Virtual Machine (JVM) will share these security settings.


## Upgrade Prerequisites
Before you perform the upgrade, create a backup of your files, data, and configurations in case you need to restore them.
## Upgrade Steps
Follow these steps to perform the upgrade:
  1. In Anypoint Studio, create a Mule project.
  2. In **Mule Palette** , click **Search in Exchange**.
  3. In **Add Dependencies to Project** , enter `FTPS` in the search field.
  4. In **Available modules** , select **FTPS Connector** and click **Add**.
  5. Click **Finish**.
  6. Verify that the FTPS Connector `mule-ftps-connector` dependency version is the one you are upgrading to in the `pom.xml` file in the Mule project.


Studio upgrades the connector automatically.
### Verify the Upgrade
After you install the latest version of the connector, follow these steps to verify the upgrade:
  1. In Studio, verify that there are no errors in the **Problems** or **Console** views.
  2. Verify that there are no problems in the project `pom.xml` file.
  3. Test the connection to verify that the operations work.


### Reverting the Upgrade
If it is necessary to revert to the previous version of FTPS Connector, change the `mule-ftps-connector` dependency version in the project’s `pom.xml` file to the previous version. You must update the project’s `pom.xml` file in Anypoint Studio.
