Defence will shift about 400 more IT systems to Linux-based servers in the coming months as it nears completion of a decade-long upgrade of its radar surveillance systems.

Contractor BAE's Linux systems engineer, Jamie Birse, told linux.conf.au attendees that more than 1000 operational, development and research systems were in line to be shifted off proprietary Tru64 and VMS-based systems onto Intel-based servers running Red Hat Enterprise Linux.

More than 600 systems have already been migrated.
