    Hi Ivugrinec, jumping over more than 2 main releases is not supported. Also, 15 and 18.4 codes have major changes, instead try to move first to: 15.1X53-D58 or 15.1X53-D590, and then move to 18.2 before getting to 18.4.

     

    See:

    https://www.juniper.net/documentation/en_US/junos/topics/topic-map/upgrading-and-downgrading-to-upgraded-bsd.html

    ""You can skip no more than two releases when upgrading (or downgrading). That means you can upgrade only to one of the three releases subsequent to your current release. If you want to upgrade across more releases than this, you need to perform multiple upgrades.""

    The 2 release jump limitation, is more or less precautionary.  The jump should actually work, but are you sure you have the right EX2300 image?  I think you would be best to land on (at least right now) 18.2R3-S1.  The image name should have "arm" in it.  The image I found for EX2300 (includes -C and EX3400 as well) looks like this:

     

    https://cdn.juniper.net/software/junossr/18.2R3-S1.7/junos-arm-32-18.2R3-S1.7.tgz?SM_USER=rmcgovern&__gda__=1568686764_5e9150fea13f7b11a11cc00f896c451a

     

    I suspect you are not using an EX2300 image, and the reason why xe-0/1/1 is not valid in the config.  No idea what your /tmp/image2.tgz is???

     

    You should also look at this KB - https://kb.juniper.net/InfoCenter/index?page=content&id=KB31201&actp=METADATA

     

    Good luck

    The solution was not to jump from current firmware directly to 18.4R2. I had to go step by step. First i updated to 15.1X53-D590 and then to 18.4R2.

    Everything wen't smoothly this way.

    I have the same issue but 15.1X53-D590 is no longer available for download.
    Is there a work around?

    You can request no longer posted versions by opening Juniper support case.

    Since you won't be able to the graceful upgrade path you would need to do a full format install off a USB drive.

    This will erase the current configuration and format the internal drive.  So first you would need to remove and save the current configuration file.  Download the file:
    /config/juniper.conf.gz

    Create a bootable USB for the ex2300 and do the format install on the desired version.
    https://supportportal.juniper.net/s/article/EX-How-to-format-install-EX2300s-and-EX3400s-via-USB?language=en_US

    Then you can upload and replace the config file with the original one and reboot the ex.

    Or upload the original file renamed as the first rollback configuration: juniper.conf.1.gz

    Then in configuration mode do a rollback 1 and commit.

    So we had this problem and it was related to not having  unit 0 on all the non AE interfaces. It seems that on different versions the system will hceck to make sure you have certain things set in your config and sometimes they dont.
    We got by this one of two ways, either set unit  0 on all the interfaces or re did the no-validate command when we did the upgrades. Both worked for us.
    Of course we still did not make more than that 2 version jump just to be safe.

    ge-1/0/5 {
    traps;
    unit 0 {
    family ethernet-switching;
    }
    }
    ge-1/0/6 {
    traps;
    unit 0 {
    family ethernet-switching;
    }
    }
    ge-1/0/7 {
    traps;
    unit 0 {
    family ethernet-switching;
    }
    }
    ge-1/0/8 {
    traps;
    unit 0 {
    family ethernet-switching;
    }
    }
