"Not where, but how."

Translation: Nicht wo, sondern wie?

[Uberharm]

I'd say: nicht wo aber wie

[mizinamo]

When you are correcting something and replacing the first word with a correction, then the construction "not A but (instead) B" is nicht A sondern B with sondern.

[Mwalek]

Could this also work; "Nicht wo, doch wie"? Thanks

[mizinamo]

No.

You need sondern in this kind of construction.

[Mwalek]

Ah yes! I missed this — vielen dank!
