Fail to transfer whatapp chat - no option to restore I want to transfer my whataspp chats from my galaxy s3 mini to my new galaxy A3.

I followed the guide (I think!)

I backed up my chats and then copied the database file over onto my pc. The files all look like msgstore.db.crypt.crypt8 or with a date msgstore-2015-03-26.1.db.crypt8.

When i installed whatsapp on my new phone there was no database file so i created one.
I then tranferred the msgstore files into it. 

When i went though the verification process... i didnt get any option to restore and i have none of my chats... 

now ive seen that my first overnight back up is in a new folder logs and is backed up as  whatsapp-2015-03-29.1.log.gz

what have i done wrong? what can i try?
Thanks in advance
