Upgrade from version 8.4 to 9.3

[lockoom]

I have few questions concerning upgrade from version 8.4 to 9.3
1. Is it possible to upgrade directly from 8.4 to 9.3?
2. Or should I have to go full path 8.4.0 -> 8.6.0 -> 9.0.0 -> 9.0.1 -> 9.2.1 -> 9.2.2 -> 9.2.3 -> 9.3.0?
3. Maybe I could skip some steps?
4. What is a preferred method of doing upgrade? Is updating via Plesk web panel (Plesk Control Panel Updater) reliable?

I'm pretty scared of bad things that could happen

Just run /usr/local/psa/admin/sbin/autoinstaller and follow to instruction. You can upgrade it directly to 9.3.
