When moving an entire DBXL installation to another server, you can follow these steps:
1) Restore the databases QdabraDBXL and QdabraSamples to the new location (or whatever you chose to name them)
2) Install DBXL, pointing the installation to the restored databases.
3) Open the DBXL Administration Tool (DAT) from the new server.
4) Edit/Save each document type you have. This is required so all the DBXL data connections in your templates get updated to reflect the new site url.
