How to revert back to a previous version of Pyramid

On this page, you will find how to revert back your Pyramid version to a previous one.
This was written for 'Pyramid 2018' but for later versions simply look for folders named just 'Pyramid'.

Pre-requisites:

  • A backup of the Pyramid repository from the version you wish to revert back to.
  • The installer of the version you need.

First Steps:

  • If it wasn't already done, If you're using an IMDB (In-Memory DB), backup the 'imdata' folder to restore later.
    The default location is: "C:\Program Files\Pyramid 2018\repository\imdata"
  • If you're using publications, backup the below folder to have the ability to review and open published publications:
    "C:\Program Files\Pyramid 2018\repository\general"
    This step should be done on each Pyramid server.
  • Copy the machine key from config.ini 
    (C:\Program Files\Pyramid 2018\config.ini).
    After the reinstallation copy the old machine key to the new config.ini
    look for:
    [machine]
    installType=1
    host=myPyramidserver.com
    machineKey=0e93adc283152805cceb676d9a38ec1e

Uninstall:

  • Remove Pyramid 2018 completely from the server(s) through the control panel.

Re-install:

  • Restore the backup of the Pyramid repository.
  • Install the previous version of Pyramid
    * Use the option of using an existing DB and point it to the restored DB.
  • After the installation is complete, copy the old machine key into the new config.ini
  • Remove all the new server entries in the table "server_instances" (In Pyramid repository) (check according to the date they were added)
  • Restart Pyramid 2018 services and try to log in.
  • Restore the contents of the IMDB and General folder to their relative locations.
