When the transfer was made public SCO announced that it would work towards merging UnixWare with its [[OpenServer]] [[System V#SVR3|SVR3.2]] based OS,<ref> {{Citation |url=http://www.cbronline.com/news/santa_cruz_hp_novell_carve_up_unix_between_them |title=SANTA CRUZ, HP, NOVELL CARVE UP UNIX BETWEEN THEM |publisher=Computergram International |date=21 September 1995 |access-date=1 November 2008 |archive-url=https://web.archive.org/web/20120927022431/http://www.cbronline.com/news/santa_cruz_hp_novell_carve_up_unix_between_them |archive-date=2012-09-27 }} </ref> but the first release of UnixWare from SCO was version 2.1 in 1996. At the release of UnixWare 2.1 it was announced that the proposed UnixWare/OpenServer merger was known as project '''Gemini''', to be available in 1997 and a 64-bit version of UnixWare was to be developed for 1998.<ref> {{Citation |url=http://findarticles.com/p/articles/mi_m0EIN/is_1996_Feb_12/ai_17963591 |title=SCO Unveils Enterprise Class Operating System; Release of SCO UnixWare 2.1 Paves Way for Next-Generation UNIX Systems |publisher=Business Wire |date=12 February 1996 |access-date=1 November 2008 |archive-url=https://web.archive.org/web/20090124165357/http://findarticles.com/p/articles/mi_m0EIN/is_1996_Feb_12/ai_17963591 |archive-date=2009-01-24 }} </ref> One controversial change was the adoption of an OpenServer-like user licensing policy. The Univel and Novell releases of UnixWare allow 2 users on the personal edition or unlimited numbers of users on the server edition. With UnixWare 2.1 the server edition includes a license for up to 5 users. Customers wanting more users could purchase 10, 25, 100, 500 or unlimited user license extensions.<ref> {{Citation |url = http://www.krsaborio.net/research/acrobat/1990s/9602_unixware.pdf |format = PDF |title = SCO UnixWare 2.1 Application Server |publisher = SCO }}{{Dead link|date=July 2018 |bot=InternetArchiveBot |fix-attempted=yes }} </ref> SCO released three updates to UnixWare 2.1. UnixWare 2.1.1, released in 1996 achieved [[Single UNIX Specification|Unix 95]] branding.<ref> {{Citation |url=https://www.edn.com/sco-announces-unix-95-compliance-update-to-its-operating-system/ |title=SCO Announces Unix 95 Compliance Update to its Operating System |publisher=EDN |date=26 November 1996 |access-date=10 January 2024 }} </ref> UnixWare 2.1.2 and 2.1.3, available in 1998, are largely bug fix releases. In 1998 [[Compaq]] released a package known as the Integrity XC consisting of a [[single-system image]] [[cluster (computing)|cluster]] of [[Proliant]] servers with a version of UnixWare 2.1, [[UnixWare NonStop Clusters]].<ref> {{Citation |url=http://in.rediff.com/computer/1998/aug/11compaq.htm |title=Compaq Integrity XC server launched |date=1998-08-11 |access-date=7 October 2008 }} </ref> The first results of the Gemini project were made available in early 1998 as UnixWare 7.<ref> {{Citation |url = http://www.tparker.com/unixware_7_mar_98.htm |title = UnixWare 7: revolution or revision? |publisher = Timothy Parker Consulting Incorporated |date = March 1998 |access-date = 1 November 2008 |archive-url = https://web.archive.org/web/20071114172859/http://www.tparker.com/unixware_7_mar_98.htm |archive-date = 14 November 2007 |url-status = dead |df = mdy-all }} </ref> SCO named the kernel version [[UNIX System V#SVR5_/_UnixWare_7|Unix System V release 5]]. The system is largely based on UnixWare 2.1, with features for driver compatibility with OpenServer, allowing use of OpenServer network drivers. System administration utilities from OpenServer, '''scoadmin''', replace the original UnixWare '''sysadm''' utility. Major new features of UnixWare 7 include multi-path I/O, large files and file systems and support for large memory systems.<ref> {{Citation |url=http://www.cbronline.com/news/sco_gemini_to_debut_as_unixware_compaq_gets_chummy |title=SCO GEMINI TO DEBUT AS UNIXWARE; COMPAQ GETS CHUMMY |publisher=Computergram International |date=19 August 1997 |access-date=1 November 2008 |archive-url=https://web.archive.org/web/20100218150745/http://www.cbronline.com/news/sco_gemini_to_debut_as_unixware_compaq_gets_chummy |archive-date=2010-02-18 }} </ref> UnixWare 7 lacks the [[Xenix]] compatibility features of both its ancestors.{{Citation needed|date=August 2014}} In 1999 SCO released the UnixWare 7.1 update which increased the number of editions; the '''Business''' (5-user), '''Department''' (25 user) and '''Enterprise''' (50 user) editions replace the earlier personal and server editions. The WebTop application from [[Tarantella, Inc.]] is included.<ref> {{Citation |url=http://www.cbronline.com/news/sco_data_center_unixware_to_debut_at_cebit |title=SCO DATA CENTER UNIXWARE TO DEBUT AT CEBIT |date=25 February 1999 |publisher=[[Computergram International]] |access-date=1 November 2008 }} </ref> In 2000 SCO released the UnixWare 7.1.1 update. Simultaneously the [[UnixWare NonStop Clusters]] 7.1.1+IP [[single-system image]] [[cluster (computing)|cluster]] package was released. This new package allows [[commodity hardware]] to be used as well as the proprietary Compaq hardware supported by the earlier Integrity XC product, and was directly available from SCO.<ref> {{Citation |first=Andrew |last=Orlowski |title=SCO, Compaq ServerNet-less clusters |url=https://www.theregister.co.uk/2000/06/26/sco_compaq_servernetless_clusters/ |date=2000-06-26 |access-date=2008-10-28 |periodical = The Register }} </ref>
