Reasoning that the component HAS to work, I tried a prior release - 0.5.5 transferred half my articles. Finally, I used 0.5.4. This transferred all the articles correctly.
There will be NO home page, just a 404 if your home page was originally a blog listing. Only menu links to specific articles will still work. All other blog menu links will have to be rebuilt.
This has saved me a very great deal of effort - many thanks! ( Building a new template is not very hard really either - if you could build the old ones !)
