Ingres has been around for longer than you think: about 20 years.
So, the data has been converted one time in 35 years. Pretty damned
stable if you ask me.
Another example: the on-disk structure of RDB/VMS has remained
stable ever v1.0 in 1984. That means that upgrading from
major-version to major version (even when new datatypes and index
structures have been added) is a quick, trivial process.
Companies with lots of important data like that.

ASCII will be here in 20 years. So will EBCDIC. As will UTF.

Is "common sense" really valid?
For example, it is "common sense" to white-power racists that
whites are superior to blacks, and that those with brown skins
are mud people.
However, that "common sense" is obviously wrong.
