Replace Bottom Bracket; Sealed vs Unsealed

I have a 20 year od Centurion that I have been commuting with the last 4 years.

I thought it would be a good idea to check the bottom bracket as it has never been repacked.

I was wondering if it would be a good idea to replace existing components with a sealed bearing set from Shimano or other.

Would I have to remove/replace the existing fixed cup?
