This Issue Tracker is for bug reports and feature requests only. We recommend that any software usage questions be asked on the DSpace Tech Listserv. This gives us all an opportunity to better answer your questions, and also often results in a more prompt response.

That all being said, here's a few tips on DSpace data migration.
Here's an email thread on the dspace-tech list that answers this question:
http://dspace.2283337.n4.nabble.com/Moving-data-from-one-instance-to-another-Dspace-1-6-2-td3327692.html
(In particular, see the 3rd email in the thread, which describes migrating PostgreSQL database data.)
Essentially, the DSpace data is stored in two places. (1) the Database and (2) the Assetstore folder (in [dspace]/assetstore/).
You should use the PostgreSQL database tools to migrate database date:
pg_dump: http://www.postgresql.org/docs/8.4/static/app-pgdump.html
pg_restore: http://www.postgresql.org/docs/8.4/static/app-pgrestore.html
The Assetstore folder (and all subfolders) can just be copied over as-is.
Finally, if you are actually upgrading your version of DSpace, you will need to make sure that the database gets upgraded properly by running the proper DB upgrade scripts in [dspace]/etc/postgres/
Running the DB Upgrade scripts is detailed in our Upgrade instructions: https://wiki.duraspace.org/display/DSDOC18/Upgrading+a+DSpace+Installation
In most cases, it may be easiest to *first* migrate the DSpace instance as-is (i.e. using the old DSpace version) to the new server. Make sure it is working after the migration. Then, perform a DSpace upgrade by following the upgrade instructions linked above.
I'm going to close this ticket and mark it as "answered". If you have any follow-up questions, I'd recommend posting them to the dspace-tech listserv, where we can help you out further.
