There isn’t a “way”. Just delete it before you import.
Simple and easy.
I tried that before, but it just skipped over that ID (#1).
Once an ID# was used – even if the post gets deleted – the DB will use the next number. That’s the nature of the MySQL database.
So there’s no way around it? That sucks. 😐
Why do they postIDs matter in the import?
I suppose if its really that important to you, you could import everything except your old post#1 and then just edit Hello World manually to match your post.
PostID’s matter because I’m a very (very very very) picky person who only wants her old entries’ IDs to match with her new program’s IDs (to continue the flow and to be consistant when counting).
But I’m going to do with the advice you suggested.
Check the file /wp-admin/install.php. Lines 159 through 167 insert the first post and comment.
