I have an older warehouse being converted to an public assembly arena. Does anything need to be done with the sprinkler system?

An older warehouse about 30 years old equipped with wet K=8.0 SR uprights on a system designed for baled cotton storage having a density of 0.25 gpm over 3000 sq ft with 500 hose.

I believe it is just fine just as it is and even though it is a light hazard occupancy not having QR sprinklers.

What say you?
