Hello, I've been having some issues with changing the sheet formats of some of the old drawings from 2017 that I updated now. We have a new company logo and on the old drawings it's still the old one. Drawings were forwarded to me, so I don't have the old sheet formats stored anywhere on my PC, only the new ones. When I manually search for the new sheet format and try to replace it on the old drawings, it won't work for A4 and A3 formats. If I open the same sheet format as a new document, it has the new logo in it. I don't want to create new drawings and dimension all parts once again, because there is just too many.

Any help would be greatly appreciated. Thanks!
