copy files from remote linux host to another remote linux host with one to one mapping of hosts.

I have 100 old servers having some different applications and 100 new servers as old’s replacement. I want to copy the log files of old servers to its respective new server using Ansible. How can I do it. It looks something as shown below.

Server 1_old → Server 101_new

Server 2_old → Server 102_new

Server 3_old → Server 103_new

Server 4_old → Server 104_new
