Is it possible to merge WhatsApp chat histories on 2 Android devices (but 1 account)?

If so, how?


1 Answer 1


The most realistic approach I've found is this:

  1. decrypt the WhatsApp backup file with the WhatCrypt app
  2. merge two sql databases.
  3. encrypt it

Although the approach looks promising, WhatCrypt 2.4 failed for me. (This is the most recent version for October 2019 - no updates since October 2016. It's still available via the Wayback machine.). I get "Different key file for this database". But maybe I'm simply doing something wrong.

  • I tried this few times first time I tried it long ago I got successful merge 2 msgstore.db i.e. unencrypted files but it gave me malformed database error and attempted to restore from backup to /data / data / com.whatsapp / second time I tried it WhatsApp versions were different. one was latest version and when I tried to run update, 2 update records I got constraint violation error if you had any luck let me know what workeds for you Nov 11, 2020 at 8:45
