Database Portability Database Portability InterSystems IRIS databases are portable across platforms and across versions, with the following caveat: On different platforms, any file is either big-endian (that is, most-significant byte first) or little-endian (least-significant byte first). InterSystems IRIS provides a utility to convert the byte order of an InterSystems IRIS database; it is called cvendian. This is useful when moving a database among platforms of the two types.
