Smart Updates (only available on Pro version)
Step 1: Log into Plesk dashboard. Click on WordPress on the left panel. Under your domain, toggle Smart Update button to the right to switch on Smart Update.
Step 2: At the Updates corner, click on View. You will see a list of updates available (if you have yet to update). Select the few updates that you would like to perform and allow some time for the process to run.
Step 3: Once the process completes, there will be a pop up that shows the before and after view of your website. If you are satisfied with the after (which also means the updates did not affect your website), you can proceed with the update.
