But going after its installed base rather than trying to add new customers poses a challenge for SCO: Many of its customers are small and midsize businesses with more limited IT budgets, and many SMBs that have been using SCO technologies for a long time tend not to upgrade as often as large enterprises.
One such customer is CSK Auto Inc., an auto parts retailer based in Phoenix. George Duckworth, director of store support for CSK, said the company has deployed SCO software for about 11 years in 1,125 locations in 19 Western states.
"We have one server in each of our stores running SCO OpenServer and a 16-bit MegaBASIC application running in a Xenix emulator on that OpenServer box," Duckworth said. "We are moving from OpenServer to UnixWare and hoped to have the first pilot for this installed this month." He said those moves will take place over time. "We had to come up with a way of spreading the cost out over three years or so where we could actually get it done. The first part, what we are doing now, is starting to migrate to hardware that will support the applications we want to write, while upgrading from OpenServer to UnixWare," he said.
Among SCOs large customers is Siemens AG, which uses SCO because it is flexible enough to support a number of PC architectures and peripheral devices, said Detlef Fischer, head of Siemens Power Generation, Instrumentation and Control Development division, in Berlin. Siemens uses SCO in all subsections of that division except automation, Fischer said.
Hunsaker said SCO will fight to keep its current customers from being lured away by competitors such as Sun Microsystems Inc., Novell Inc., Hewlett-Packard Co. and Red Hat Inc. "We are not going to allow them to take our customers away. We will protect them to the end," he said. "But for us to go head-to-head with them on a new customer—absolutely, thats a huge challenge."
