Direct upgrade is possible, do a test run first.
Make sure the OS is supported by both versions and you might have to
switch Java versions mid-flight.

And prior to the upgrade: Backup the SQL database of your management
server (twice). If you have a clean backup of the state in 4.18, you can
always roll back to 4.18 if needed.
