Migrating database from Vertica cluster 6 to the new Vertica cluster 7

i would remove the vertica 7 software from the target cluster, install the same version 6 as on source, run a copy cluster operation and then upgrade the target to version 7. Sounds like a lot of operations, but they are quick for the most part , except the copy itself which depends on the network bandwidth between the 2 clusters.

Thanks for your response.
