I am looking to update an old Windows Service which has been running for a couple years now with no interruption. I have updated a couple connection strings within the project, and everything seems to build fine.
Is there a way to update this service without having to uninstall and reinstall? I would rather not uninstall considering how long it has been running in a stable state.
Could I simply just Stop the Service, replace the re-built EXE and re-start?
As long as the required settings in the registry are not different you should be fine.
If possible test first on another machine.
