## Migration Start

This screen is broken into three sections.

#### Backup Current Database

This section will allow the user to export the current attributes for the VA
Department of Veterans Affairs orderable items, products and NDCs to an output CSV
Comma Separated Value file for user in a later migration effort. It is useful in maintaining the changes the user has made to the system during the transition efforts.

When the user presses the Start Download button, the system will begin collating the data and saving the information out to files on the server. At this point, the data is not being saved to a user machine but to an intermediate location on the server. It could take several hours for the download process to finish. While the download process is occurring, the migrator can check on the status of the download by pressing the Status button. This will show the current status of the download. Once the download of all three files is complete, the Save Exports button will re-appear. The Save Exports button can be used to save each of the three types of files to a directory on the browser client’s file system.

#### Export Domain Mapping

This section will allow the user to export and import the information from the FDB
First DataBank and VA domain mapping tables. It is useful in maintaining the changes the user has made to the system during the transition efforts.

The Export Domain
