The upgrade instructions indicate you can go directly from Sierra.

Make sure you understand what software won’t work anymore and have a plan to resolve. Go64 is an easy way to get a list of your 32-bit apps that won’t work.

To add to others advice given >>


Do I have a Rescue Plan In-Place. This comprises having 3 Backups using 2 methods and 1 Off Site incase of Theft, Loss or Natural Disasters.


A Time Machine Backup  is very useful and can be used to Revert to Previous Working macOS.


For addition purposes - two Tested Bootable Clones each to separate external drives. This is insurance incase the upgrades goes sideways. At least one Tested Clone and / or Time Machine Backup should be Off - Site
