Since a service is registered using its destinguished name inside the registry you only have 3 Options:

1) Uninstall old and install new with same name
2) Install new service with different name
3) Redesign old service to have a pluggable and therefore updatable design loading worker DLLs on the fly at startup (so there will be a restart only needed to load the new dlls)
