Cheers all, I am really not looking to open up any debates about the various operating systems available. What I am doing is researching a way to keep using older XP based systems without having to buy hardware or buy new Windows software. Background I've been collecting data about moving systems to a Linux based OS starting with the XP systems. There is a lot of information, enough to establish a precedent, out there. It is being successfully done internationally at the government level. Either of the free office products can handle the day-to-day tasks. Mozilla has enough products to handle browsing and email. The price tag is attractive. The learning curve can be addressed via phased in timing and peer assistance at least to start. One deal breaker is legacy software and I only can think of trying them one at a time with Wine*. Another deal breaker is various parts of the WAN access main frames (two I know of); they have to play nice together. Last deal breaker I can think of is all updates and access is IT controlled so they have to retain that. Security thoughts Let's face it, gone are the halcyon days when Apple and Linux were basically ignored by hackers, i.e. US CERT weekly posts. I have yet to find an enterprise grade anti virus / internet security program for Linux. At least one firm has expressed an interest but... Their development process would be after the fact if this idea has legs. Why here and why now I am bringing this idea here because; simply stated I've leaned to trust the community and experience of the members. I've done a bit of research including obtaining white papers for the French Police and a major German city that are and have done this respectively**. Have articles but not white papers from other nations and entities that are doing this heck even the Feds are discussing it. What I do not have is this idea being vetted by people who know how to do it, use it and just plain know a heck of a lot about it. With XP's end we have a lot of XP based systems so now is the time. But in order to make this fly, if it can, I want my ducks all lined up. Any anticipated buy in for this idea is from the cost avoidance side and maybe some good press for the powers that be. So here I am hat in hand, asking you to share your thoughts and any leads to additional information for this project. Regards, Null *There are several custom windows based programs in use. Several are huge and may not directly migrate. My thought was tweaking how these systems access our network so they keep working. **The German city took about ten years and that many millions of US$ to complete their change over.
