I've got the same issue with antelope and barracuda as several other posters seem to have.
Your database has tables using Antelope as the file format. You are recommended to convert the tables to the Barracuda file format. See the documentation Administration via command line for details of a tool for converting InnoDB tables to Barracuda.
I've seen the threads with a variety of suggestions along the lines of running a php script and I'm struggling with it.
I don't have php on my Windows server that hosts the MySQL - I'm using the workbench tool to maintain the databases.
I tried running a select statement found (http://dev.mysql.com/doc/innodb-plugin/1.0/en/innodb-downgrading-procedure-conversion.html ) to identify which tables needed fixing, but it found no rows requiring fixing. Admittedly it does seem to be instructions for an older version of MySQL - we are on version 5.6, so it may well not be looking for what I thought it was.
Can you fix the database directly using MySQL workbench without knowing which tables need fixing.
Basically can anybody point me at some WIndows based instructions for when the database is on a separate server to the Moodle.
