After reading Bill's woes with SPIN/SPOUT and the deployment in general, I figured he isn't the only one who needs to know this: 

There is an excellent deployment tool which assists both in migrations and deployments, and can take most of the pain out of the process. I highly recommend giving it a look if you need to work with a Sharepoint deployment of any size. From the website:

The K-Wise Deployer is a stand-alone environment designed for the rapid migration of documents from multiple sources into SharePoint Portal Server.

 It provides:

Migration from SharePoint 2001, file share and other sources
Mapping and analysis of content sources
Metadata creation, extraction and flexible mapping into Columns
Bulk creation of Share point Portal Server Structure: Areas, Document Libraries and Folders
Bulk and Batch check-in of documents
Taxonomy management tool

Note:  This is probably the most shameless product plug I've ever written, but hey - I love this tool.
