  1. Hi

    Thanks for this Anoop excellent article once again. I have managed to download it in production environment but our pre-prod environment is blocked. Is there any scripts etc that I use so it can download the easypayload to pre-prod please?

    Reply

  2. Since there is a client upgrade involved with this update, why do you not get the option to first deploy the client upgrade to the Pre-production collection first allowing you to first test it before promoting it to Production? I also noticed the Hierarchy Settings for the Client Upgrade still show 5.00.8913.1012 even though the clients are automatically upgraded to 5.00.8913.1026?

    1. StaffIs this after installing the out of band hotfix ? Did you try to update the client and checked the version over there?

      I could see 5.00.8913.1027 version in my console hierarchy settings-client upgrade tab
