Move an Existing Blog into WordPress Multi-Site

Move an Existing Blog into WordPress Multi-Site: "Copy Database Table Method

This was the method that I used because it was more efficient for me.

Instead of using the export/import functionality, you can also go into your server and copy all the relevant data from your old blog database tables into your new blog tables.

Here is how to do it in phpMyAdmin -

Log into phpMyAdmin.
Click on the database you want to copy (left side of screen). This is the database used for your old blog.
Click on the table you want to copy (left side of screen).
Click on the Operations tab at the top. On the right side of the screen, below the Move table to interface, there will be a Copy table to interface (example shown below). Before you copy the data over, you may first want to clear the destination table on your new blog."
