    Hi, I'm not sure if this is related to your problem, you need to upgrade to 19.5 first, then upgrade to 20.0.

    Look at the error: NavServerNotFoundException

    Please check the content of your variables, especially $NewBcServerInstance

    If that is set please check if the service is running

    I doubled checked this and the variable is right and the service is running.

    Can you show us a bit more of your powershell script?

    Other guess:

    Did you miss the "Invoke-NAVApplicationDatabaseConversion" step before upgrading the system app?

    Seems like the version of your database / the database's schema doesn't match the version of your BC20 service.

    I found what I was doing wrong, I wasn't syncing the right things. Silly mistake, but got it figured out. Thanks!
