Upgrading from Sitecore XP 9.2.0 or earlier

Remove deprecated Path Analyzer maps from the Reporting database

In Sitecore XP 9.3.0, the First Visits and Returning Visits maps were removed from the Global and the Site maps.

After the upgrade, the tree definitions for these maps are still present in the Reporting database and Sitecore XP continues to needlessly aggregate data for these definitions.

• To delete the tree definitions of the maps that have been removed, run the following query:

  
  DELETE FROM [dbo].[TreeDefinitions]
  WHERE DefinitionID IN
  ('E049AD86-D98B-4639-A450-77D1B294A270','D57B53BE-CD98-4EC4-9767-C99F8A72EC0A',
  'F2C21FD3-22C5-4F32-92AC-443984D06FC7','4118EA73-7CEE-4FBC-AECE-5693171744C7')
  

Customize the MarketingDefinitionAliasValidationRegex application setting

If you customized the alias validation expression, you must also apply the same customized expression to the MarketingDefinitionAliasValidationRegex application setting of both the CMS and xConnect websites after the upgrade:

<appSettings>
  <add key="MarketingDefinitionAliasValidationRegex" value="^[a-zA-Z0-9_\-\x20]*$" />
</appSettings>

For more information about this step, see the section Validate the marketing definition names.
