1. tried to upgrade dxa 1.5 to 1.7 [both application and cms (8.5)]
2. got messed up
3. rolled back cm changes by doing DB refresh of Dev cms. we have put uat cms db replica into dev cms
4. rolled back cms changes
5. topology manager details was not backed up before the DB refresh but cloud team helped us to set it up

post that all required items got published and can browse the website.

though following error i am getting:

    "A problem occurred while rendering this section
    Semantic schema '10182' not defined in Localization [19 ('English')]. Check that the Publish Settings page is published and the application cache is up to date."

following is error from application log:

    "2019-10-14 11:54:54,078 [10] ERROR - Semantic schema '10182' not defined in Localization [19 ('English')]. Check that the Publish Settings page is published and the application cache is up to date.
