Upgrading to HRSP without downtime
 

I received a project of a network that needs upgrading.

The previous network admin, have made one single catalyst router for the
entire network.

In the upgrade I would like to change this router task with HRSP for better
redundancy, however I would like to avoid downtime for the network.

Could I make HRSP standby address the same as the catalyst's current
Interface address, and then afterwards change the interface address and
avoid downtime for the network?
