Determine process for replacing non-build documents

[c-suh]

💡 Description

Prompted by NASA-PDS/portal-tasks#110. Looking at questions such as...

1. If the filenames of the old and new documents are different, which is used?
2. If using the new document's filename, is a redirect put in place for such cases where the URL of the old file (complete with filename) is bookmarked?
3. What happens to the old file - is it archived or held anywhere, whether locally or in a repository or other?
4. If there is no apparent Changelog, should there be one? If so, what is the process for creating and maintaining it?

If the filenames of the old and new documents are different, which is used?

The new should probably link to the old.

If using the new document's filename, is a redirect put in place for such cases where the URL of the old file (complete with filename) is bookmarked?

No. I think we keep the old version available online, we just don't link it from anywhere. We really should put this in our online archive. Not just ad-hoc store them on the website.

What happens to the old file - is it archived or held anywhere, whether locally or in a repository or other?

See above.

If there is no apparent Changelog, should there be one? If so, what is the process for creating and maintaining it?

Good point. I can add this.
