The first questions that spring to mind are
* How modified are your datasets (eprint fields, etc)
* How modified is your GUI? (template, browse fields, abstract page 
rendering, etc)
* How big is your database?

Assuming your are moving from a stock eprints (perhaps with some changes 
to the stylesheet, logos, and template files), and a fairly small 
dataset - then you can export the eprints & export the users, then 
import the users & import the eprints

I've recently done a move of a complex, extended, dataset from one 
hosting system to another.

* Install a base EPrints & check it works
* Update the various datasets & rebuild the database
* Add in the importers & exporters, the template & GUI changes, and all 
the other ancillary stuff
* test your importers & exporters
* run around your GUI, make sure everything's there.

NOW copy the old database to the new database (at 
MySQL/PostgreSQL/MongoDB level) and the Disk0/ tree to the new 
filesystem... and get the system to regenerate views & abstracts...
