IT temp-to-hire contract positions, are they worth the risk?

I work for a pretty reputable bank who was just bought out, sadly. I’m in a nice, under paid IT LAN analyst position which was stable, but recently has become unstable. This gives me an opportunity to look for jobs that pertain to where I really want to go, which is the network admin side. Unfortunately I have no backend experience, so I’ve been putting it off, until I got a call yesterday. I have an interview with a contract to hire co who is looking for a junior network admin position in a college down the street…..sounds awesome, its a 4mo contract to hire position, think its worth the risk?
