We have tables with MyISAM. The are out of sync, the number of records is different on each cluster node

I need the tables to be InnoDB and in sync. Those two statements crashing.
CREATE TABLE test ENGINE=InnoDB SELECT * FROM nrmtz.tablename1;
ALTER TABLE tablename1 ENGINE=InnoDB;
Are there other ways doing it without crash?
