I'd be lying if I said I document anything.
Generally I just compare the two templates and take it from there. A lot of the time when it is a minor upgrade (eg 3.5.3 to 3.5.4) they list exactly what needs to be changed in each template so I just apply that. If I have to revert I create a child style first, make the changes on there, then export it and import it to overwrite the existing style.
