    Upgrade path from 7.6.6 to 7.15.5

    I'm trying to upgrade from 7.6.6 directly to 7.15.5

    Is this possible?

    I've attempted to do this and getting the following error:

    2020-07-27 11:17:00,855 [P16680/D2/T8] ERROR Umbraco.Core.Persistence.UmbracoDatabase - Exception (33c9f9f5). System.Data.SqlClient.SqlException (0x80131904): Invalid object name 'umbracoUser2UserGroup'.

    I've set the useLegacyEncoding to true but it won't accept my admin account to authorise the upgrade.

    Any help would be much appreciated.

    Thanks

    Rich

    Hi,

    Have you read https://our.umbraco.com/documentation/Getting-Started/Setup/Upgrading/version-specific

    I would probably step to 7.7.13 as there is a user group change in 7.7 - then you should be able to go straight to 7.15.5

    HTH

    Thanks for your help but installed it this way: Sebastiaan Janssen 03 Oct 2017, 16:11:21

    Go into web.config and set the umbraco version to empty (so: ) Change the connection string and make it empty too (so: ) You will then asked to install Umbraco again, enter your user details Click on the customize button to provide the SQL connection details Umbraco will detect then that you already have a database and will try to upgrade it You MIGHT get an error the upgrade, I clicked "Back" and tried again and then it worked
