Estimating the Disk Space Required for Upgrading

Before you perform an upgrade of Microsoft® SQL Server™ version 6.x to SQL Server 7.0, you must have enough available disk space. This is important if you intend to perform either a one-computer or a two-computer upgrade.

The SQL Server Upgrade Wizard estimates how much disk space is necessary to upgrade the SQL Server 6.x server to SQL Server 7.0. The wizard examines the current SQL Server 6.x installation and estimates how much disk space the SQL Server 6.x data will occupy in the new SQL Server 7.0 server.

You can estimate:

• The size of SQL Server 7.0 databases.
• The size of SQL Server 7.0 logs.
• The amount of disk space required for tempdb.

Note The SQL Server Upgrade Wizard estimates the disk space required; it cannot give an exact requirement.
