I am trying to take the course for AI Fabric and it says that i would require a Enterprise cloud Trial account to complete the course. My question here is that i already have the Community edition installed on my laptop and if i request for a Enterprise cloud Trial account what happens to my Community edition? Will that be overridden? Also when my Trial expires after 60 days will be i able to use my previous Community edition without any issues on my same laptop machine? Since the Trial License will expire in 60 days and if I still want to use AI Fabric can i request for Trial again?
