This step-by-step article describes how to plan for a large site UNIX-to-Windows migration. When you migrate from a site that is hosted by multiple UNIX computers, you must identify the method that is used in your site, and then select a strategy for the migration.
If the site hosts multiple Web sites across a number of servers, the migration is straightforward. You can create new virtual Web sites under Windows to host each site. You may find that you can reduce the number of physical servers that is required in this installation by placing more sites on to the same computer. This also reduces the administration of the new service, because you can control more sites from the same computer.
Use a different method if the site is hosting only one Web site, or a number of departmental sites that make up a whole domain site such as www.microsoft.com, downloads.microsoft.com and msdn.microsoft.com. In this scenario, migrate the sites in the same physical formats that are used under UNIX, by using redirection to redistribute requests around the servers.
If a site is hosted in its entirety by a number of computers, each of which connects to the site contents from a central repository, you can use the same method under Windows.
You can use this to your advantage, by migrating individual virtual Web sites to their new Windows host, and then using redirection on the UNIX hosts to point to the new servers as each one becomes available. By using a staged migration, you can check each area of the site without changing the whole Web site.
Use Services for Unix to access the same NFS-shared folder, and use this as the document root for your site in Internet Information Services (IIS).
