How to upgrade Firebird 4.0.1 to 4.0.2

Here is the way I upgraded my Firebird 4.01 to 4.0.2 on Ubuntu Linux. Used the same procedure to upgrade between 4.0 RC 2 to 4.0.1
I could not find documentation on upgrades between point releases but this works for me.

  • stop all services using Firebird
    • in my case since I am using supervisor supervisorctl stop all
  • stop Firebird service
    • service firebird stop
  • move existing installation directory as backup
    • mv /opt/firebird /opt/firebird_old_4.0.1
  • download binary to temp directory
    • wget
    • tar -xf Firebird-
  • run installer
    • ./
    • when asked I use the same as previous SYSDBA password
  • stop service the installer started automatically
    • service firebird stop
  • copy configuration files and security database from previous
    • cp /opt/firebird_old_4.0.1/firebird.conf /opt/firebird
    • cp /opt/firebird_old_4.0.1/security4.fdb /opt/firebird
    • copy other files you want to keep like databases.conf and any extra plugins,etc
  • start firebird service and the applications that depend on it
    • service firebird start
    • supervisorctl start all
