Updated to the 9.4 lightroom Classic and wondering how to retrieve my presets

Hi everyone,

I had to update my lightroom as my older version could not support my camera files and was tired of converting them. I first had to update my mac to Catalina in order to do so. When all was finished updating, I opened my last catalog with Lightroom 9.4 and I saw that my presets did not transfer. I researched how to find my presets in order to import them in my new lightroom, following all of the right steps ( User - Library - Appications - Adobe - etc) and all "Develop presets" or "user presets" folder were empty. I tried opening my older version of Lightroom CC and it keeps crashing - it is not compatible anymore. I am not restoring my computer to the older software, so my question is : 

Will I be able to export my presets from my older lightroom CC, then re-upgrade my computer software to Catalina, then import this presets folder to the new Lightroom 9.4 ? Will the presets be compatible? I simply cannot imagine losing all of my editing workflow.

Thank you for your help!
