Starting with AIMMS PRO 24.5.1, the postgresql database version is updated to Postgresql 16.2 for Windows installation. This means when upgrading to AIMMS PRO 24.5.1 and newer, you will need to migrate your pro postgresql database, which adds a step to the upgrade process.

The following steps explain how you can do this using AIMMS PRO Configurator >> Backup Management:

Preparation and backing up the old database:

  • Before you proceed to installing the newest PRO version open the pro Configurator and take a database backup using Configurator >> Backup management >> Backup Now
  • Make sure backup is created (i.e. compressed (.zipped) folder under C:\ProgramData\AimmsPRO\Backup\
  • Copy (or take a screenshot of) all Configuration Settings (Connection configuration, PRO Configuration and Backup management tabs) such that you can copy them to the new installation.

Install a new PRO - 24.5.1 or newer (new postgresql db - postgresql 16.2):

  • Start Configurator
  • Go to Connection Configuration >> Test Connection >> Save Settings
  • Go to PRO Configuration >> Change PRO Server License, PRO Client Server with your licenses
  • PRO Configuration >> Add your Worker Profile
  • Save All Settings

  • Go to Backup Management >> Backup now
  • Make sure backup is created (C:\ProgramData\AimmsPRO\Backup\

  • Now go to Configurator >> Backup management >> Backups from Current Version of AIMMS PRO Platform
