Hello,
The best way to move your data is to backup your files on the first computer and move the resulting zip file to the second computer.
The backup file is a regular zip file, its location is specified in My Money preferences.
Here is a relevant page from our manual explaining backup procedures.
http://wiki.mthbuilt.com/Back_up_your_Money_fileOnce you located your backup file please transfer the zip file to the new computer, unzip it there into a relevant folder (C:\Documents\Financials for example, or similar) and start MyMoney.
Please use File-File Open menu to navigate to the location of the expanded zip file,
Thank you
MTH Team
