From the manual: http://dev.mysql.com/doc/refman/5.1/en/alter-table.html
For example, to convert a table to be an InnoDB table, use this statement:
ALTER TABLE t1 ENGINE = InnoDB;
The outcome of attempting to change a table’s storage engine is affected by whether the desired storage engine is available and the setting of the NO_ENGINE_SUBSTITUTION SQL mode, as described in Section 5.1.11, “Server SQL Modes”.
https://dev.mysql.com/doc/refman/8.0/en/sql-mode.html#sqlmode_no_engine_substitution
When you create the table do you get any warning about the Engine type being unavailable?
