What must be indicated upon upgrading classified information?

When classified information is upgraded, it is essential to provide clear and specific markings to ensure proper handling and identification of the document. Indicating portion markings and the date of the upgrade is vital for distinguishing which parts of the document contain higher sensitivity levels compared to the original classification. This allows anyone accessing the document to understand the current classification status and to manage the information appropriately.

Portion markings help identify which parts of the content are classified and at what level, ensuring that individuals who handle the document are aware of the classification boundaries. The date of the upgrade is also crucial, as it informs users when the reclassification took place, providing a sense of the timeline and relevance of the information's sensitivity. Incorporating both of these elements supports compliance with regulations governing the protection of classified information and maintains the integrity of the classification system.
