Advice on a half tone pitch raise

[Vinny Samarco]

Hello Everyone,
I have been asked to do a pitch raise on a console.
When I last saw it, as it was changing hands, the physical condition seemed
to be good, as far as strings, tuning pins and bridge pins.
Since I am blind and cannot use an etd, I will be tuning aurally.
I once was told that when you have a large pitch raise, you need to do it in
octaves first.  By this I mean, all the As Bs etc. so as not to damage the
plate.
As far as where to set the pitch for the first pass, I was thinking of using
my 442 fork, and setting the rough tuning a few beats above that.
Any correction and advice would be greatly appreciated.
