Juan,
That's not a rookie question. The "new exam" date has been a PMI moving target since it was announced in mid 2019.
The "new" exam will start 2 January 2021 according to PMI. Go here
www.pmi.org/certifications/types/project-management-pmp
and on the right side of the page is "Important PMP Updates" and follow the links.
It will be PMBOK 6 even for the "new exam" although I have heard that after 2 Jan 2021, it will be much more agile oriented.
Hope that helps.
Harry
