Follow the steps given below :
Take a backup of your sticky notes data on your current PC using the Notezilla Troubleshooter app.
On your new PC, you can download and install Notezilla from our website http://www.conceptworld.com/Notezilla/

After this run Notezilla Troubleshooter again to restore your backed up data on the new PC.
If you are already syncing notes with the cloud, then you don't have to run Notezilla Troubleshooter to backup and restore. You can simply go to the Sync option on the new PC and download all your notes from the cloud account.
Thanks.
