I don't think I am quite making myself clear. I will try again.
We have an existing site that has been extended for several years. While it has currently been upgraded (in dev) to 4.4, we want to take full advantage of the module builder. We have even experimented with the module builder and feel very comfortable with it. However, due to the site's evolution over the years, we essentially want to start "from scratch" with a brand new project extending as much as possible with the module builder. In fact we already have a brand new site about 50% complete in functionality and visual design. The thing that is missing is a way to take all our existing generic content, blogs, libraries, and images from the OLD site and migrate them to the NEW site. True, we could simply save it all out and manually copy or recreate it in the new site, but my goal was to find a way to save us all that work.
Again, the migration tool looks like it would be perfect if it were available in other migration versions (e.g. 4 to 4.4, old URL to new URL, etc.), but it is not. So, in lieu of that, I was wondering if there is any other way to do that (e.g. code scripts, SQL scripts etc.) I could open a support ticket, but I thought I would check with the community first.
So, again...any ideas? Has anyone else tried something like this? Is there an "open-source version" of the migration tool so I could modify it to suit our need?
