Migration from i5800 to r5800

Hello,

My approach would be to a create new tenant in r5800 assign the same vlans as current cluster but with new self ips. 

Add these new self ips to whatever fw rules you may have for the old ones.

Then add the new tenant as member of the existing cluster.

Sync and confirm that new node is able to communicate with as many pools as the active one.

During a maintenance window failover to new node and confirm functionality.

If everything is fine proceed with the other r5800

At the end you will have a cluster of 4 and you can start decommissioning i5800.

Another option is to shutdown standby i5800, use it's self ips to new r5800 tenant and add it to the cluster. Confirm again connectivity, failover, check functionality etc.

This way you do need new ips.
