I want to migrate a volume (vol0) from old 2550 running Ontap 8.2.2P1 7-Mode(filehost) to a new 2650 running Ontap 9.3P4 (cltaoc01)
I created a new volume type DP in th new cluster, then I created a peering in transition mode, then I've set a snapmirror and when I try to initialize it return the "State: unitialized" and the "Last Transfer Error: Transfer failed", the logs are below from both machines.
Besides, I have set the hostname and IP address in the /etc/snapmirror.allow and snapmirror state is on, in the 8.2.2.P1. Both machines have the snapmirror license.
Any clue why this this migration is failing? Thanks,

7MTT is using the same TDP SnapMirror under the hood. According to IMT, 7MTT CBT from 8.2.2 to 9.3 is supported which means TDP should also work. This sounds more like some networking issue between systems.
