Offline Upgrade of Zerto Appliance

  • I need to upgrade our Zerto Virtual Appliance from 10.0 U1 to latest 10.0 U2.


    The problem ist that we have no direct internet connection. I found an article how to configure a proxy for all pods, but still the update fails.

    DNS is also resolved via proxy, so ping or lookup of domains will fail.

    I downloaded the upgrade package and .sig manually and put it in the upgrade directory, but in between the upgrade process the job exits with the following error:


    ERROR: Failed to upgrade to zvm version
    ERROR: Failure reason: “Required TCP resources cannot be accessed: zertodownloads.s3.amazonaws.com:443, zapps.zerto.com:443, keyserver.ubuntu.com:80”


    Is there a way to work around this problem?


    do you have a solution for that? I need also an option to upgrade them offline. I received all time same failure message: Upgrade validations failed. Reason: Required HTTP resources cannot be accessed: https://httpredir.debian.org/, https://security.debian.org/, https://zvml-upgrade.s3.amazonaws.com/

    There should be a much easier way to apply updates. The ZVMA is not a very good experience so far.

    Hello Colleages,

    as far as I know:


    ZVMA Offline Mode

    ZVM Appliance now supports both online and offline clean deployment from Zerto version 10_U2 Patch 1. You can then upgrade to any later version. This feature is available from version 10_U2 Patch 1.
