Congratz, I stumbled on this thread way too late. If you need help with any other ISACA cert let me know... i sadly have most of them. Also have CISSP and ISO27001 LA.
I've got an interview tomorrow to move from an Internal Audit role into IT Audit for the same company. If I am succesful, CISA and CISM are some of the certs available. CISSP is also another one that has been offered. I will pursue CISA but, unsure which to go for between CISM and CISSP.
