I am Unable to restore my whatsapp chats while switching to new phone

i switched to a new phone. I copied whatsapp folders- Databasse and media to the laptop. The database file has correct name as suggested by whatsapp faq- msgstore.db.crypt and it is version 12 only. But when i install whatsapp it does not take that local backup and asks to check google drive. I don’t have backu on google drive. Later i tried new idea- I disconnected internet after verifification of mobile number and yes so it prompted – >backup found- Restore> i tapped restore, but still my chats didn’t backedup, the restore processing also did not took lace, i turned on internet after tapping restore. what’s the matter? please help. I have some really important stuff. You all are tech enthusiast here. i hope you can help me in this minor problem. I have local Backup, i have mobile, i have aplication. What else is needed??
