Experience in IT business analysis and project management is useful to make a transition into MC. You really have to shpw the business side of things in your projects. For example, by implementing IT system XYZ, you were able to enable a key business strategic imperative ( such as increase enter new markets). The above is an example, but gives you an idea of how you have to spin it going from IT to MC. I assume that your time in IT was not technical, but rather business facing (and therefore being all about the business and their issues). If it was technical, its going to harder, and you'll be best suited for engineering or some technical MC roles such as operational MC roles in say telcommunications ( but employed by MC).The MBA will definately help.Else, you could always try IT consulting ( ACN, CGEY, IBM, Etc). They too have many 'business facing' IT roles. Just be sure what you want: business facing or technical ( not always easy to transition between the two).
