CMigrator proved to be the solution. What impressed me so so much was not only the availability of such a product but also the PEOPLE behind the product. Having some technical issues (not being a technical whizz) I asked Compojoom if they could help and I said I was happy to pay for this. Daniel promptly suggested I call them in Germany via Skype which I did and about an hour later they had fixed the issue. I am not sure if it was of my doing or something within CMigrator that had caused the issue but either way they would not accept payment! How much does that tell you about the confidence you can have in this product and Compojoom - and Compojoom's OTHER products as well (by the way, I have CComment as well and this also imported over a thousand comments from WP without a hitch - remember, if you are going to import articles from WP or Drupal etc you will want to preserve your comments as well and this product does it for you).
I cannot recommend Compojoom highly enough and I have had experience with a very large number of Joomla extensions. Well done Compojoom and thank you.
While SP Upgrade does not attempt to migrate extensions, I would prefer to do the extensions manually than use something with appears inherently unstable and does not maintain the integrity of your content ids.
So well done to the developer! A small price to pay Thank you.
I deal with people all over the world, most of whom treat you as a faceless entity which I guess is understandable. However, I can tell you that these guys (Shawn and Helix) have REAL HEART. They are incredibly decent and professional and from what I can see and from what I have read have developed a superb product that everyone should use if they want proper protection.
I cannot be more enthusiastic about OSE. To buy their products is to buy CONFIDENCE and VALUE well in excess of the dollar price.
