In addition to the hardware and software requirements for an installation of Microsoft® SQL Server™, the computer must meet these requirements for an upgrade.
|Operating system||Microsoft Windows NT® Server Enterprise Edition version 4.0 with Service Pack 5 (SP5) or later.
Windows NT Server version 4.0 with SP5 or later.
Windows NT Workstation 4.0 with SP5 or later.
Internet Explorer 5.0 or later.
|SQL Server 6.5||When upgrading SQL Server version 6.5 to an instance of SQL Server 2000 on the same computer, you must have applied SQL Server 6.5 Service Pack 5 (SP5) or later. When upgrading SQL Server 6.5 to an instance of SQL Server 2000 on a different computer, you must have applied SQL Server 6.5 Service Pack 3 (SP3) or later.|
|SQL Server 7.0||SQL Server 7.0 (at any Service Pack level).|
|Network protocols||Named Pipes.
SQL Server 6.5, SQL Server 7.0, and SQL Server 2000 all must be set to listen to the default pipe, \\.\pipe\sql\query. Named Pipes is required even for a tape backup upgrade.
|Hard-disk space||No additional hard-disk space is required when upgrading from SQL Server 7.0 to SQL Server 2000.
When upgrading from SQL Server 6.5 to SQL Server 2000, however, you need approximately 1.5 times the size of the SQL Server 6.5 databases.
