Adding Vcenter after ESXi's were added individually

I'm taking over some of the management  for Solarwinds at my company as we kind of had a few people all doing their own things who never fully learned it and we wanted to reduce waste and clutter. I noticed that our ESXis appear to have added individually and not all of them correctly. Our VMs have also all been added manually as nodes. I assume I will want to remove the ESXis that are not set up correct before adding Vcenter itself to map them all automatically. Will that impact the ESXis that were added correctly or any of the VMs on those ESXis that were already added manually?
