Any idea how long the upgrade takes on a VM?
Direct upgrade not possible.
You need first to upgrade to v10.1, then to 10.2 and finally to 10.3.
Each upgrade takes about 10 min to upload the software and then 20 min for the actual upgrade. During the upgrade all connection to the server is lost. No progress indication. Only Ping is working.
