ABC-Z of moving from .com to .org

Hi Guys,

I am wondering if someone can give me a literaly ABC of moving a blog from wordpress.com to www.remarpro.com

Currently I have my blog on wordpress.com
https://booquepress.com

I already have a domain on wordpress.com – I want to keep it but running on www.remarpro.com

I hope this all makes sense, I attempted to move the blog before and somehow it worked the only problems is, I started to freak out because
A. Somehow my stats disappeared
2. No followers
3. Any changes I made on .org did not appear on booquepress.com – I believe I did something wrong or missed something. I don′t want to go through motions of registering a new domain, I have worked really hard on booquepress.com and want to just move over swiftly.

Please can you help?

Thanks
