To transfer your data to a new computer you need to back up your data first. This can be done by opening the application from your old computer, go to File > Backup data. The default folder where the program is backing up the data is C:\Program Files\Golf Diary\BACKUP. After your data is backed up, copy the content of the folder to the new computer using a USB stick or a cloud storage service, into the same folder as above (you should copy the data after you installed the application on the new computer). After the data is copied, open the program (on the new computer) go to File > Restore Data and choose the same folder. It's advised to use the same version of the application to avoid compatibility issues.
