Hi,
In looking over my past posts which were originally imported from WordPress, I don’t think everything imported. Ditto with my Twitter archive, there’s a lot there, but not everything. My thought is that maybe something went wrong and I should just run the imports again, but will this wind up duplicating posts? Also, do I get a message when the import is successful? I think I may have navigated away from the import page figuring it’d take a while for everything to be pulled in.
It wont create duplicates, although the two imports work a little differently.
Twitter import will clear the old tweets and copy them again. It doesn’t take as long on subsequent imports because any photos that were copied won’t be copied again.
WordPress is a little smarter and will only add new posts that don’t already exist on subsequent imports, looking at the permalink for the post.
