Back Up Before Updating

!

Create a backup first

Before making any WordPress changes, including updates, create a backup so the website can be restored to its previous state if something goes wrong during the update process.

Update WordPress Core

WordPress software updates are managed from the WordPress admin panel. When an update is available, the admin panel displays a notification.

  1. Log in to the WordPress administration panel.
  2. Go to Dashboard > Updates.
  3. Click Update to version X.X.X to install the available WordPress core update.

  2. Click Update Plugins or Update Themes.

Update Server Components

Server components such as the application server and database are updated from the Virtuozzo Application Management dashboard through the Redeploy action.

  1. Find the required WordPress environment component in the platform dashboard.
  2. Click Redeploy.
  3. In the redeployment window, select the latest required server version. For the application server, this includes selecting the required PHP version.
  4. Confirm the redeployment.

Scaled WordPress clusters

When redeploying a scaled component, use sequential deployment to update instances one by one. This keeps the WordPress website available while the component instances are being updated.

WordPress data is preserved

The source documentation states that clicking Redeploy does not affect WordPress data because this operation updates only the server software.

Expected Result

WordPress core, installed plugins, and themes are updated from the WordPress admin panel, while the underlying application-server and database software can be updated through the platform Redeploy workflow. For scaled components, sequential deployment can keep the site available during server updates.
