Upgrade to Catalina

I have been working on a High Sierra Hackintosh since May 2018. I need to upgrade to at least Catalina to keep up to date with my architectural software. I have already successfully changed my graphics card from a GTX 1050 to a Radeon RX 570.
Motherboard: Gigabyte GA-H270-HD3P
CPU: i7-7700
Should I do anything else before trying the Catalina install? IE: update Clover?
