moving backup server

[Zappy]

Hi ,
need to move backup server from server1 to server2
all my backup client point to pbs.mydomain.com (server1)

so here what i am planning :

1. Install pbs on server2
2. rsync data from server1 to server2
3. shutdown server1 and rename/reip to server2

will all the API token move as well , or i need to move all the file in /eyc/proxmox-backup. as well ?
just want to verify if my plan make sense
