Is there any downtime required during an in-place upgrade?
Yes, there is a small amount of downtime as per the services that will be upgraded and it will depend on multiple factors such as the resources on the server, number of domains, mailboxes, databases... so the time that it takes to reconfigure each service and complete the server upgrade may vary from few minutes to hours. Generally, only Plesk UI service will be down for the time of upgrade. Other services can be down no more than 1 minute.
