Migrating from Monolithic to Client+Core

Install The Core


Migrate Database

If your Core is going to be on a different computer/under a different user account than your monolithic client was running on, you'll probably need to migrate the data.


For SQLite, it's as simple as copying/moving a file. The default locations are:

  • Windows: %APPDATA%/
  • OS X: ~/Library/Application Support/Quassel/quassel-storage.sqlite
  • Linux: (One of the following)
    • ~/.config/
    • /var/lib/quassel


pg_dump -C dbname | ssh -C remoteuser@remotehost "psql dbname"

Change Default Login Password

The monolithic client creates a default user called `AdminUser`, with a randomly generated password. The password isn't used in the monolithic client, and there's no way to find out what it is as the password is encrypted in the database. So we need to overwrite it. Run the following command:

  • Windows (x64):
    • Start > Run
    • Type cmd.exe then click ok.
    • Type "C:\Program Files (x86)\Quassel\bin\quasselcore.exe" --change-userpass=AdminUser then press enter.
    • Follow the instructions to change the password.
  • OS X:
    • Open Terminal
    • Type quasselcore --change-userpass=AdminUser then press enter.
  • Linux:
    • Open Terminal
    • Type quasselcore --change-userpass=AdminUser then press enter.
