Your customer is migrating data from a legacy FAS8020 system that runs ONTAP 9.5 software to a new AFF A250 MetroCluster over IP configuration.
In this scenario, which two methods would be supported to migrate the data? (Choose two.)

One supported method to migrate data is using a host-based copy migration method. This method is versatile and can be applied in various situations regardless of the hardware or ONTAP versions. Another supported method is configuring a SnapMirror copy between the FAS8020 and the AFF A250 systems, as SnapMirror allows for data replication across different ONTAP versions and different hardware. The controller swap method is incorrect as it is used for replacing controllers of the same model, and creating a 4-node cluster with the vol move command is not feasible due to ONTAP version compatibility issues between the FAS8020 and the new AFF A250.
C & D Controller swap it'snt correct its a process for replace a controller of same model 4 Node cluster can be possible but you need a Switch for cluster and the ha pairs must be in the same ontap version and suppose that the A250 is in a newest version due to 9.5 it's out of support. So it makes sense to me host-based migration SnapMirror you can configure with the newest versions of ontap
A250 not support 9.5
D only makes sense if the A250 is on 9.10 or lower since 9.5 can't talk to 9.11, which seems to be what the hardware comes with out of the box today. The 8020, however, CAN be upgraded to 9.8, which the A250 also supports and thus a 4 node cluster *could* be made if switches are available. So B/C/D are all valid answers depending on circumstances.
C & D are always possible, so it must be these two
Controller upgrade is not supported from FAS8020 to A250 so A is wrong, https://docs.netapp.com/us-en/ontap-systems-upgrade/upgrade-arl-auto/decide_to_use_the_aggregate_relocation_guide.html#sys_commands_95_97_supported_systems B is also wrong because AFF A250 Metrocluster IP is supported on ONTAP 9.8 and later Correct is CD
