The SCO Group continued the development and maintenance of OpenServer. On June 22, 2005, OpenServer 6.0 was released, codenamed "Legend", the first release in the new 6.0.x branch. SCO OpenServer 6 is based on the UNIX [[UNIX_System_V#SVR5_/_UnixWare_7|System V Release 5]] kernel, a merged codebase of [[UNIX System V|UNIX System V Release 4.2MP]] and [[UnixWare|UnixWare 7]].  OpenServer 6.0 features multi-threading application support for C, C++, and Java applications through the POSIX interface. OpenServer 6 features kernel-level threading (not found in 5.0.x).

Some improvements over OpenServer 5 include improved SMP support (support for up to 32 processors), support for files over a terabyte on a partition (larger network files supported through NFSv3), better file system performance, and support for up to 64GB of memory.

OpenServer 6.0 maintains backward-compatibility for applications developed for Xenix 286 onwards.<ref name="os6qsg">
