    It seems the issue was something on the self-ip, it worked!

Hi NiHo, I have a suggestion for you based on my personal experience. The steps I follow in a similar situation are: OLD CLUSTER 1) change the ip (with a fake ip) in the old VS 2) delete the ip address from Virtual Address list NEW CLUSTER 3) set the ip address in the new VS When set the new IP address, the F5 send a gratuitous arp to the upstream network, so the arp tables would adjust automatically, and no mac duplication would occour.

 

regards

 

Leonardo

    No, I have just deleted the ip address in the virtual address list. In my experience this work fine.
