Thanks, Jocelyn!

I tried altering the engine to InnoDB but was not allowed. Hmm.
Then I decided to just drop the table to have mysql_upgrade create it again. Now mysql_upgrade complains that the tablespace for that table exists and I need to drop it. But:
MariaDB [mysql]> ALTER TABLE innodb_index_stats DROP TABLESPACE; ERROR 1146 (42S02): Table 'mysql.innodb_index_stats' doesn't exist [mysql]> DROP TABLE innodb_index_stats; ERROR 1051 (42S02): Unknown table 'mysql.innodb_index_stats' MariaDB [mysql]> CREATE TABLE `innodb_index_stats` ( -> `database_name` varchar(64) COLLATE utf8_bin NOT NULL, -> `table_name` varchar(199) COLLATE utf8_bin NOT NULL, -> `index_name` varchar(64) COLLATE utf8_bin NOT NULL, -> `last_update` timestamp NOT NULL DEFAULT current_timestamp() ON UPDATE current_timestamp(), -> `stat_name` varchar(64) COLLATE utf8_bin NOT NULL, -> `stat_value` bigint(20) unsigned NOT NULL, -> `sample_size` bigint(20) unsigned DEFAULT NULL, -> `stat_description` varchar(1024) COLLATE utf8_bin NOT NULL, -> PRIMARY KEY (`database_name`,`table_name`,`index_name`,`stat_name`) -> ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin STATS_PERSISTENT=0; ERROR 1050 (42S01): Table '`mysql`.`innodb_index_stats`' already exists
I tried stopping the server, deleting all files in /var/db/mysql/mysql/innodb_index_stats.* and restarting, but I still see the same behaviour above.
Answering my own question: I ended up solving my problem with the following: * stop the server * copy in /var/db/mysql/mysql/innodb_* files from a different 10.4 server where these tables were already InnoDB * start the server * drop the tables * re-run mysql_upgrade Thanks for the hints, everyone!
