+        Problem:
+        Need to change class ArtifactEntry property 'created' type from 'date' into 'datetime'.
+        "ALTER PROPERTY ArtifactEntry.created TYPE datetime" fails to update property type.
+
+        Solution:
+        Apply sequence of two statements.
+        1. "DROP PROPERTY ArtifactEntry.created"
+        "Removes a property from the schema. Does not remove the property values in the records,
+        it just changes the schema information. Records continue to have the property values, if any."
+        For details see: https://orientdb.org/docs/3.1.x/sql/SQL-Drop-Property.html
+
+        2. "CREATE PROPERTY ArtifactEntry.created datetime"
+        "Creates a new property in the schema"
+        For details see: https://orientdb.org/docs/3.1.x/sql/SQL-Create-Property.html
+
+        Property values will retain previously existing data, but will have a new type 'datetime'
