I have been trying out 1.7 on my iMac, but I first turned off syncing. I continued to maintain my 1.6 on my MacBook. Now I'm ready to go to 1.7 on my MacBook, but what I'd like to do is to force the iMac database to be overwritten by the MacBook one after I update the MacBook to 1.7 - rather than having a 2-way sync occur. How can I best do that? Thanks!
