 # Upgrade
 
+To upgrade your PMM instance, go to **PMM Configuration > Updates**. Here, you can view the current PMM Server version, check if your instance is up-to-date, and see the timestamp of the last update check.
+
+If an update is available, simply click the **Update** button to install the latest version.
+

+
+You can also check a summary of this information on the **Upgrade** panel on the Home page.

 ## Plan the upgrade order
 
 ### Upgrade PMM Server first
 
-Make sure to upgrade the PMM Server before you upgrade the PMM Client.
-
-Ensure that the PMM Server version is higher than or equal to the PMM Client version. Otherwise, there might be configuration issues, thus leading to failure in the client-server communication as PMM Server might not be able to identify all the parameters in the configuration.
+Always upgrade the PMM Server before you upgrade the PMM Client.
+Ensure that the PMM Server version is equal to or higher than the PMM Client version. Otherwise, configuration issues may arise, potentially causing failures in Client-Server communication, as the PMM Server may not recognize all the configuration parameters.
+
+### Migrating from PMM 2
+
+When upgrading PMM from PMM v2, follow the following staged approach: 
+1. upgrade to the latest PMM v2 version
+2. Proceed to upgrading to PMM 3. 
 
-For example, for a PMM Server version 2.25.0, the PMM Client version should be 2.25.0 or 2.24.0. If the PMM Client version is 2.26.0, PMM might not work as expected.
+Make sure you have access to the machine where PMM Server: 
+1. run docker exec -t <pmm-server> supervisorctl stop all to stop all services of pmm-server container
+2. run docker exec -t <pmm-server> chown -R pmm:pmm /srv to transfer ownership of all directories and files located in /srv directory to pmm user
+3. stop and remove pmm-server container (docker stop pmm-server && docker rm pmm-server )
+4. pull a new docker image for PMM Server v3 (once it goes GA, it will be docker pull percona/pmm-server:3 )
+5. run a new container based on v3 image ( see above) while remembering to pass the same pmm-data volume to it (docker run -d -v pmm-data:/srv ... percona/pmm-server:3 )
 
-### Staged upgrade approach
 
-When upgrading PMM from older versions (2.30.0 and below), we recommend following a staged approach: first, upgrade to version 2.33.0, and then proceed to the latest version. 
 
 This sequential upgrading process ensures that PMM's internal components are migrated and updated correctly.
 
 ## Update the Server
 
-!!! caution alert alert-warning "Known issues for older versions"
-    - Upgrading to PMM 2.32.0 from older versions fails. We recommend upgrading directly to2.33 or latest version. For more information, see the [troubleshooting topic](../how-to/troubleshoot.md#pmm-server-fails-while-upgrading).
-
+!!! caution alert alert-warning "Known issue for older versions"
     - PMM versions prior to 2.33.0 may not show the latest versions available with instances created from the AWS marketplace in specific environments, including AWS. For solution, see the [troubleshooting](../how-to/troubleshoot.md#pmm-server-not-showing-latest-versions-available-with-the-instances-created-from-aws) section.
 
 
-Client and server components are installed and updated separately.
-
 PMM Server can run natively, as a Docker image, a virtual appliance, or an AWS cloud instance. Each has its own installation and update steps.
 
-The preferred and simplest way to update PMM Server is with the *PMM Upgrade* panel on the Home page.
