<human>: Can you condense the text into a few key points?

I'm a web developer and my company runs a blog for this guy. He was one of our first customers back when it was just 3 of us. Well he's been posting and running his blog for about 4 years and had a total of 189 posts in that time. Recently he came to us because he is publishing a book and wanted some help with online marketing for it. Well we looked at his website and realized it was on an old Wordpress version that was 2 years old and the theme he was using was just as old and discontinued so we figured instead of trying to do a backup and upgrade we would just export everything and create a new site. 

So i spent most of yesterday creating the site and then getting the plugins and theme put in place. I tried to upload the content the first time and it only got to 10 posts before breaking. Sadly i didn't notice and went forward with forwarding the domain name to this new server. 

Last night i notice that it only has 10 of 189 posts. Well i figure thats no good i'll just re-upload them in the morning. However, I forgot to turn ***off*** the subscription feature, which emails his contact list of 202 people every time a new blog post is up. Mid upload process I get an email from a very angry woman who just received 80 emails from this guy. I disable the plugin appologize, but sadly I think there are 202 people who will probably be to pissed about 90 emails to want to buy this guys book.
