The context you suggested here is unsufficient. My answer is based on previous documents I have dealt with before bearing similar content. Now "Therefrom" is referring to something else that is mentioned in your content which you're working on and I assume it is maybe a validation or a checking of a document and its copy for instance or anything (this depends on the your document's nature), and what confirmed this for me is the expression "of the whole of such original" which makes me believe me that this is a validation/checking of a some document copy and its original in some records.

I hope this helps! If not, please share more information so I can assist.

Good luck!
