The Intergraph RIS client product, includes the risunload and risload utilities, which can be used to dump data out of the database or load it back in.
A risunload file is portable. You can do a risunload from one type of RIS-supported database and risload into another.
To do a risunload or a risload, RIS must be functional and the schema must work (the Data Definition operation from within RIS Schema Manager must not return any errors). If the schema is broken, a risunload is not possible.
The risunload utility can be run interactively or from a command line. However, there is no reason to perform risunloads of the database (as a separate step outside of PDS archival) unless you are moving between database types.
