    Umbraco 7 to 8 upgrade issue

    Hi,

    We're trying to upgrade a v7 website (latest version of 7) to v8.

    We're getting the following error:

    The database failed to upgrade. ERROR: The database configuration failed with the following message: Cannot rename datatype alias "Umbraco.MemberPicker2" to "Umbraco.MemberPicker" because the target alias is already used.This is generally because when upgrading from a v7 to v8 site, the v7 site contains Data Types that reference old and already Obsolete Property Editors. Before upgrading to v8, any Data Types using property editors that are named with the prefix '(Obsolete)' must be migrated to the non-obsolete v7 property editors of the same type. Please check log file for additional information (can be found in '/App_Data/Logs/')

    What is the difference between Umbraco.MemberPicker and Umbraco.MemberPicker2 and how is best to rectify this? I think there are a few other Umbraco types I have this issue with so would be good to know how to get past this.

    Thanks

    Is this a case of deleting the existing MemberPicker data type?
