Site URL: http://www.learntoplaymusic.com/store/

Hello World!

I have a client website (www.learntoplaymusic.com/store/) with magento 1.9 engine, but this is very old and needs updating. I plan to move it to squarespace so that it is easier for me to manage it, the question is, how to migrate so that all the data is not lost.

thanks
