Hi!
I have the moodledata and the backup of a database from an old moodle website. The website used 3.6.3+ (Build: 20190508). I don't have the moodle code of this site. Aside from this, I have a moodle site, using Moodle 3.9.2 (Build: 20200914). Is it possible to open and view the content of the old site using the newer website?
