Upon upgrading from 21.4 to 22.1 and later, the following error may be seen in tomcat-stdout.log:
com.appian.data.migration.AdsSchemaException: Schema: DesignObject, Details: The stored version (2021_08_10_terminal) could not be found in the migration path
In Appian 22.1 and later, the DesignObject Schema was updated to use a different version than what was introduced on Appian 21.4. This causes the above error to appear on startup, however the error has no effect on customer environments.
This issue has been hotfixed via AN-203503 in Appian 22.1.490.0 and later and 22.2.180.0 and later.
This article applies to customers upgrading from Appian 21.4 to Appian 22.1 and later.
