I'd start by reading the PMBOK to see if the process lights you up, and then find PM Network magazines to get an idea of what PMs do.
In my last position (medical education industry) I led a team of 8 PMs, and one was a telecom retread. I only took him on as a consultant to cover excess workload because he was out of work and he was willing to assume the risk of fitting in. After a few months, he showed his value and I hired him. He's now 3 years on that job, and doing great. I then interviewed another telecom person trying to get in PM (hoping to get a winner again), and he had great technical skills, but little going for him in personality and drive.
There are lots of areas where you can apply PM where you don't need technical skills. Soft skills are arguably more important than the IT skills. It's your personality you'll use more than your technical skills.
