Switching domain to my new wordpress website.

Hi,

Not sure if i’m in the right support forum but here goes…

My current website is built and hosted with Weebly, but now I have made a wordpress website to replace the old one. Thus I have a few questions about domain transfers.

1) Will I loose my google positioning when I swap it over? I’m currently #1 on google for a few searches and would like to keep it that way!

2) What is the best way to direct my domain to my new WordPress website? FYI: My domain is with crazydomains.com and my hosting is with 1&1.co.uk. I do not want to transfer the domain to 1&1, I just want to make it point to my new site.

Thanks!
