i have 2 big tables in mysql

[majed17]

Peace,
history_old.ibd is over 5 GB
history_uint_old.ibd is almost 4 GB
other history tables that are under 1 GB
are they needed? if not how to remove them on zabbix 6.2?
the database was stable before the upgrade but now it is growing quickly.

I think that everything "_old.ibd" was created as a backup. These tables do not consist in Zabbix database structure.
How to delete it? use SQL queries:

DROP TABLE history_old;
DROP TABLE history_uint_old;
