Changing table type from MyISAM to InnoDB

Question

I wonder if I convert some tables from MyISAM to InnoDB, will it cause any corruptions of data?

I am in need to convert some tables to InnoDB so I can use transaction, but they are holding very important data so I'm not sure if I should do the conversion or not.

While changing the database engine of a table is a simple and common task which should cause no corruption, the only way to guarantee no corruption can occur is to first make your own backup.
