Migrating unresolved comments to a revised PDF document
To import comments to a PDF document after the document has been revised, use the Migrate Comments feature.
This feature searches the revised document for specific word groupings and structural elements to place comments
in the correct location.
Note: Untagged PDF documents lack the internal structure necessary to correctly place imported comments in a
revised document, so results may be less reliable than in tagged documents. (See
Tagging Adobe PDF documents
Text comments that reference particular words, such as highlights, squiggly underlines, cross-outs, and insertion
carets, appear within the word grouping where they were originally placed.
Drawing markups, stamps, and notes appear in the same structural location as they did in the original document.
For example, if the comment was placed between a tagged text block element and a figure element, the comment
tries to locate those tagged elements in the logical structure order of the revised document.
If the revised document no longer contains the original word groupings or logical structure order that the comment
references, the comment will appear on the same page as the original document, or on the last page if the
referenced page no longer exists. If the word groupings for text edits can't be located, the text edits are converted to
note comments. Circle, polygon, rectangle, and stamp comments do not search for word groupings or logical
structure order. These comments always appear on the same page as the original document, or on the last page if
the referenced page no longer exists.
Comments are transferred to the source document to make revisions.

1. In the revised PDF document, choose Comment > Migrate Comments.
2. If the PDF file is open, choose it from the pop-up menu, or click Browse (Windows) or Choose (Mac OS) to select
