delta service
(OP)
I have a 400A 120/240V delta service in a building. It feeds 3 phase and single phase panels in the building.
I will bring a new 1200A, 120/208V and I wand to feed the existing panels from the new switchgear.
Whant kind of transformer do I need to feed the old panels?
Thank you.

Another question will be: can a buck-boost transformer be used?
Thank you.
RE: delta service
Yes, boost transformers (auto transfromer)can also be used to boost 3 phase 208V to 3 phase 240V. I would also separate 120V loads from the delta service and re-feed them from new 208Y/120V service.
There can be a few options, I would suggest you hire a consulting engineer and review options along with costs.
