How to Export ChatGPT Conversation and Continue It in a New Thread?

I have a long ChatGPT conversation that is getting too large to continue smoothly. Is there currently a reliable way to export ChatGPT conversation data from one thread and use it to continue the same context in a new thread without losing important details? I am not looking only for a full account data export. I am specifically trying to find the best workflow to export ChatGPT conversation history from a single thread and keep working from that context in a fresh chat. Has anyone found a good way to do this?
