Here's a question that should be simple but after a lot of searching
the answer still eludes me.

This is a small environment, using a single server to host latest
versions of SharePoint Portal and a few SharePoint services sites
using SQL 2000. There is no customizations done as yet but we have a
few thousand documents in the library. No security or access rules
have been applied to the documents as yet.

We now have a new server to host the same Sharepoint environment as
described above and want to transfer all of the documents from one to
the other server. The old server will be retired.

Given the simplicity of our requirement, what would our best method
to transfer the documents. Should we just use the Windows Explorer
or would we use SMIGRATE or ???
