Converting a huge myisam table to innodb (9 replies)

I have a huge myisam table (~30GB on disk) that I need to convert to innodb.
On a test machine, I tried using "alter table", which took about three days to complete.
That won't work at all, the system is live and I have a window of about four hours.

I guess the first question is, what information do I need to provide so that the good folks here can help me?

Thanks!
