    Get error "/Account/AccessDenied" when upgrading from v9 to v10

    I have followed the steps here to upgrade from v9 to v10:

    https://docs.umbraco.com/umbraco-cms/fundamentals/setup/upgrading/version-specific#9.latest-to-10

    and also this for Forms

    https://docs.umbraco.com/umbraco-forms/v/10.forms.latest/installation/version-specific#version-10

    After fixing some coding issues, I run the site and start the upgrade process ... a few moments later I get an error

    "HTTP Error 404.15 - Not Found The request filtering module is configured to deny a request where the query string is too long."

    enter image description here

    If I try running the site again I get this: enter image description here

    I have seen this https://our.umbraco.com/forum/using-umbraco-and-getting-started/109358-umbraco-upgrade-9-10-causing-redirect-to-accountaccessdenied-during-upgrade but I don't want to do unattended upgrades. Also, I tried it but still got the second error screen when I ran the site.

    There do not appear to be any error messages in the Umbraco log file.

    Hi Gordon,

    Not too sure what's going on with that querystring value (!) but the migration plan error is one that's popped up a few times.

    Have you had a look at something like the following, might set you on the right path:

    Cheers,

    Simon

    Hi Gordon,

    The migration state problem you see, might be a nuget package for some umbraco releated packages like Forms. If you are using Forms etc. then make sure to have the upgrade version of your packages, follow the umbraco version. Otherwise umbraco migt want to upgrade to a newer version, than what your other packages might be.
