Hello Unix Experts,

I'm going to be graduating with a CIS (Computer Information Systems) degree in the coming year. I have been offered an internship with a job title of Unix Administrator under a well known company. I understand that Unix is used for high-end servers in many large corporations, but the market share is gradually declining to its competitor (Linux) (based on articles and statistics that I have read).

If in the next 5 to 10 years Linux becomes dominant over Unix would it be easy to transition from being a Unix Administrator to a Linux Administrator? I know that the underlying foundation of both OS's are the same, but would the differences be too overwhelming to make that transition? Any insight would be appreciated.
