Deciding Between SCO and Linux?

wolfbane01 asks: "I spend some time giving tech suggestions to a medium sized business firm (~100 employees) with a large amount of demand placed on their file server. Their current server is a dual Pentium 500 with RAID array and they are looking to upgrade it. The dilemma is the current server OS is running SCO OpenServer 5.0.5, and their new raid array requires 5.0.7. Their programmers have demonstrated that a Linux box can process records much faster, but are still worried about the investment and potential problems that switching OSes would entail. I have already mentioned the cheaper price and the community availability when problems come up, but what other reasons have Slashdot readers come up with for a switch? What arguments am I forgetting that make Linux more attractive then SCO? Should I advise against switching to Linux and advocate them sticking to SCO? Is SCO going to even be in business long enough to make the upgrades product cycle?"

Summary: you have a working SCO 5.0.5 system, required hardware upgrades are driving a minor software upgrade to 5.0.7 with presumably low associated risks.

Question: is it worth a major software change to Linux with high associated risks? This change is unplanned and the programmers have already said they're worried about potential technical problems.

Answer: no. You shouldn't be using a required hardware upgrade to drive a major software change. That's a bad practise to get into. You should be approving the minor software upgrade to SCO 5.0.7.

However: given the lower TCO of Linux and the proven higher performance with your application, you should also be proposing a long-term project to evaluate a migration to Linux. The evaluation should include a risk assessment, full technical approval from the programmers, consideration of knock-on costs like training and support, etc.

Never use minor changes with low risk to drive major changes with high risk. It makes you look like a cowboy. If the SCO system was failing and there was an impending deadline and the 5.0.7 software upgrade carried a high risk... THEN and ONLY then would a hasty Linux migration have any merit. I doubt that's the case. Don't put your balls on the block when this should be a simple low-risk software upgrade.
