Can i restore more than one msgstore.db.crypt7 file in whatsapp? Recently changed my old phone to new one (Samsung to MotoX). During this old to new phone conversion phase (for one month) I didnt use Whatsapp at all.
Before totally stopped using whatsapp on my old phone, I Had taken whatsapp database backup from my old phone.
But when I got my new phone, in a hurry I totally forgot about whatsapp backup (which i had taken from old phone) and installed whatsapp on my new phone.
As per process it's got created new msgstore.db.crypt7 (just for that one month, during I didnt use whatsaap at all) file in database folder of whatsapp on my new phone.
Then I recollected about old whatsapp backup file (from old phone), so i uninstalled whatsapp on my new phone, again took a backup of newly created msgstore.db.crypt7 (from new phone), rename it as msgstorenew.db.crypt7 and kept in the same database folder of new phone.
To get all the older whatsapp message, i have kept old backup file msgstore.db.crypt7 (from old phone) in database folder of new phone and reinstalled whatsapp again on new phone.
I successfully able to restore all my old whatsapp messages.
But now along with the old whatsapp messages, I want to restore newly created whatsapp backup file (for one month) as well which i renamed it as msgstorenew.db.crypt7 (in the same database folder), so that i can have all the messages (old+new). But i am not able to find any option for the same.


Kindly help.

Thanks.
As you can read in the wahtsapp faq, 


  Current chat history will be lost upon restoration.


Anyway, you could follow these steps.
For every older conversation:

1)Use the "email conversation" function:


  To export a copy of the history of an individual chat or group, you
  can use the Email Chat History feature:
  
  Tap and hold on the conversation or group. Select Email conversation
  Choose whether to Attach Media or not. An email will be composed with
  your chat history attached as a .txt document.
  
  If you choose to attach media, the most recent media sent will be
  added as attachments.


2) Send the composed email to yourself.

After you did that for every older chat, restore the newer ones using your backup.
This way:


You will be able to read your newer messages on whatsapp normally.
You will be able to read your older messages opening the attached .txt file in the emails that were composed
