Hello Wiets Wilken,

In my opinion, you should uninstall your Easyblog from your live site and remove all the Easyblog table ( #__easyblog_xxx* ) from your database first.
Then follow my instruction to import all the Easyblog data from your old site to live site.

Ideally, it's best that you create an export sql dump file through phpmyadmin and export the all Easyblog tables over. Here's the general guideline that you could use.

1. Open up PHPMyAdmin tool that is provided by your hosting provider and open up your current site's database.
2. Make a sql dump for all the Easyblog tables that has the prefix of #__easyblog_*
3. Download the .sql file and save it on your desktop.
4. If your new site's database prefix also uses the same prefix , then you can skip this part. However, if you are using a different database prefix, you'll need to edit the .sql file that you've just downloaded, and do a search and replace of jos_ with your new database prefix.
5. Open your PHPMyAdmin and this time, open up your new site's database.
6. You should see an import link at the top. Click on that, and click on browse. Select the .sql file and click the run import button.
7. Install the latest EasyBlog on your new site.

Hope this help.
