Single Host configured to Multiple Target Environments

Hi Experts,

I have a scenario in our Production environment.

We are creating True Production environment to point our Production website to resolve Target Catalog Data corruption due to lower environments pointing to Target Production.

When we do this we need to move our prod host to point to True Prod and hence bringing downtime to Target Recs in Production website.

Is there a way I can configure a single Host to multiple Target Environments so that the behaviors gets populated and then switch to true prod environment.

Any suggestions really appreciated.

Thanks,

Karnakar
