From Cubase 1.0 (1989) to Cubase VST 5.1 (2001) the file format used by Cubase was .all (Cubase song) and .arr (Cubase arrangement) files. It was only possible to open files on a Cubase version identical or newer than the version that saved the file. The upgrade to a new version of Cubase was not a big issue.

Starting with Cubase SX 1.0 (2002) the file format was changed to .cpr (Cubase Project File) and .npr (Nuendo Project File). It is possible to open files on a newer and, in some cases, the older version, for example a file saved in SX2 will open in SX3 and work perfectly if the vst set is the same, there have also been reports that a project from SX3 will open in SX2 for example.

Cubase SX 1.0 was the first Cubase version not to open Cubase VST songs and projects. Cubase SX 1.0 allows you to import VST projects and save them in the new *.cpr format. However the import feature doesn't work very well.

Cubase SX 3.1.1 (2005) was still able to import Cubase VST songs but with very limited ability.

Some of the important data not imported from Cubase VST songs:
tempo
some tracks parts
mute/unmute track option

Cubase 4 was the first Cubase version not to support the import of Cubase VST songs and projects. To give the ability to import older Cubase VST projects and songs Steinberg decided to make the previous Cubase SX3 and Cubase SL3 versions available as a download. But, because of the limited import capability of Cubase SX, Cubase 4 users are forced to use Cubase VST to work on old Cubase VST files or to manually export single tracks and then create a new project in Cubase 4.

It has also been reported that there are backward compatibility issues between different Cubase versions using the *.cpr format.
