[Setup] site migration + synchronization (subversion)

[Robert Nagle]

I'm looking to deploy a plone site.

A few questions.
1. if I migrate a plone site from one hosting service to another, how? 
(Has anyone written about it before?) Is it simply a matter of uploading 
Data.fs to the appropriate spot and making sure the same product 
versions are installed? How do people handle the migration of ZPTs and 
skins? (i.e., migrate them together with zodb or make some attempt to 
migrate them separately).

2. I've seen deployment strategies that mention using subversion. I'm 
still a subversion newbie , so bear with me.
In Matt Rohrer's installation how-to, he describes the advantages of 
using subversion to keep track of products.

I'm a little confused here. Will i need to create a subversion server on 
both my laptop and my deployment server?  Or only on my laptop? (Right 
now I don't even have a deployment server to deploy to).
