Cacti 1.3.0 - devel - Database clear/re-initializing

[Atreides]

Hello,
Is there a way to clear/re-initializing the database? Or if I drop the database and reimport a clean one do I lose all the graps? I'm having some huge mysql problem after I did a php upgrade_database.php --forcever 1.2.14 from cli. To be exact, after that, mysql is killing the CPU and sometimes the server became unavailable. I've looked for errors, and I see tons of it , all mysql related, but dont know how to fix and what.
Centos 8, mariadb 10, php 7.2, cacti [ 1.3.0 - Dev 1ccc5f893 @ 2020-08-31 01:51 ], spine 1.2.8


Also some errors in httpd log :

CPU usage is extremly high : 10:33:25 up 12:41, 1 user, load average: 26.18, 28.84, 29.93
Also the webpage is unavailable everytime I try to delete graphs(504 gateway timeout).

Is not a production server, so I dont mind losing graphs for a day or even all, as long as it will repopulate those graps.
