It's hard to answer a question like this without adequate information. I, for one, would not be willing to take a chance on answering it without some knowledge of the stringing scale. One 1884 Weber grand I scaled had (original) tensions upwards of 240 lbs through the tenor section tri-chords and upwards of 300 lbs (each) on some of the bi-chords. I don't have any Weber upright scales handy to compare but if they scaled their uprights as they did their grands I'd want to be some cautious about raising anything. Even though the increase in overall tensions from A=435 to A=440 is not all that great I'd still want to look at the scale and the plate before doing anything radical. And, if I were restringing the piano, I'd not want to do so without rescaling the thing.
