Should I use the probes or keep existing

[stubro]

As I am upgrading from an existing Apex system should I use the probes that came with the new Apex or should I use the existing BRS lab grad probes and existing Apex ones? Maybe save the new ones as spares? Thoughts? ORP is the only new one for me.

How old are your current probes? Personally I would use the new ones as they are upgraded double junction probes. Most people that upgrade sell the old probes with the apex.
