# Upgrading from Client SDK 3 to Client SDK 5

## About this task

Upgrading from Client SDK 3 to Client SDK 5 requires you to have a source version of PingAccess that you plan to upgrade to or past a target version of PingAccess 7.3 or later.

To upgrade the AWS CloudHSM Client SDK from 3.x to 5.x to integrate it with a target version of PingAccess 7.3 or later:

## Steps

1. Ensure that the source version of PingAccess that you plan to upgrade to or past version 7.3 is running.

   |   |                                                             |
   | - | ----------------------------------------------------------- |
   |   | Do not stop this source version of PingAccess until step 7. |

2. Stop the CloudHSM 3 standalone client with the `sudo service cloudhsm-client stop` command.

3. Move or delete the `/opt/cloudhsm` file.

   |   |                                                                                                                                                                                                                                                                       |
   | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
   |   | You can't complete step 4 if you already have the AWS CloudHSM client installed because of the structural changes made to the client between 3.x and 5.x. If you are upgrading from PingAccess 7.2 or earlier, you must remove any existing CloudHSM client software. |

4. Install the JCE 5 client.

   For more information, see [Install and use the AWS CloudHSM JCE provider for Client SDK 5](https://docs.aws.amazon.com/cloudhsm/latest/userguide/java-library-install_5.html) in the AWS CloudHSM documentation.

5. Copy the `cloudhsm-5.x.0.jar` file into the `pingaccess/deploy` directory of the target version of PingAccess that you plan to upgrade to.

6. Run the PingAccess upgrade.

   For more information, see [Upgrading PingAccess](../upgrading_pingaccess/pa_upgrading_pa_landing_topic.html).

7. Stop the source version of PingAccess.

   For more information, see [Stopping PingAccess](../installing_and_uninstalling_pingaccess/pa_stopping_pa.html).

## Result

You have upgraded to your target version of PingAccess and integrated AWS CloudHSM Client SDK 5 with it.
