+If a file from an earlier version of LyX is opened *and saved* with
+any version of 2.3.x, then the original file will automatically be
+backed up. The backup file will be found in the backup directory, if one
+is set under Tools> Preferences> Paths, or else in the same folder as
+the original file, if no backup directory is set. The filename of the
+backup file will be:
+    ORIGNAME-lyxformat-NUM.lyx~
+where NUM is the LyX format number of the original file. In the case of
+2.2.x file, this will be 508, but in the case of older files it will be
+different.
