The cluster joining method is always a good option if you have the luxury of additional self IPs for new devices. In addition, you may need to accommodate new self-ips in the communication matrix (routing & FW) to ensure a seamless migration. 

When you add new nodes to the cluster, always remember,

  1. Both i & r series are running the same version. If iSeries is running on v16, upgrade it to v17 as rSeries does not support v16.
  2. Sync-Only & Sync-Failover device groups are set to Manual sync
  3. Run the gtm_add script from the new nodes to pull the GTM config from iSeries.
