Switching to InnoDB, what I need to know? (no replies)

So, I got this job as a sysadmin/dba and among other things I need to change a DB's engine from MyISAM to InnoDB.

I would be really greatful if somebody with more experience could outline or link to important things I need to know. This is a rather large DB (2.4GB) running on a VPS. I need to do:

1. Switch to InnoDB without messing things up
2. Optimize the server and DB for InnoDB

I can ofc read and google, but i'd love to have something like a checklist to make sure i'm not forgetting anything important.

Thanks a lot
