I greatly appreciate your detailed reply. I took a backup of my database and all the files and set it up on my localhost using WAMP, then what i did was i took sql database and replaced all the “wp_” with a new prefix and uploaded in my localhost Database. And it worked. The only thing, was that there was a error showing up in the widget area, so then i placed new widgets and the error disappeared.

I did the same with the live server, and it worked. One thing is that if people want to do it this way, they need to make sure that, they shouldn’t upgrade wordpress in the process.

Yes, there will always be issues if you do it incorrectly Gowtham.

I suggest you to copy your site with the exact database in your PC or Mac, see this post: http://www.blog.web6.org/copy-live-wordpress-blog-to-computer/

That post I use to copy this blog in my localhost, and then you can try to change your database one by one, and see how it works, if you change all correctly, your blog in localhost will be fine, if not, then something is done incorrect. But at least, your “online” blog will still work, only site in localhost breaks.

I hope this work.

Thanks for the tutorial. But will there be any issues, if i download the complete database and open it will a text editor and find and replace all the “wp_” to a new prefix and upload the file again?

Thanks, Kimi. Worked perfectly.

One suggestion. You could just copy the tables to the same db but with the new names using phpmyadmin. Then, no need to backup!

Just a thought.

Excellent tutorial! Thanks a lot for making this available. The only one thing that remains to be mentioned is that you may only use letters, numbers and underscore. I had to do it all over again, because I used a prefix that contained a special character. ;)

Also, it’s definitely not a bad idea to put your site into maintenance mode before to work on the database.

Man, I am really happy it worked so smoothly.

Thanks a lot!

Keith!

Did you manage to change all the database prefix? Honestly, I am still afraid if I had to change my database prefix, but I suggest everyone to backup database first, just incase..

I hope your database has any prefix you want by now.

Thanks, Keith!

Hi Kev!

I am so glad the video could help you, and the most part, you fixed your database prefix error, the database itself is very crucial to our blogs.

Thanks so much for leaving your nice comment,

Have a great week, Kev!
