Migrating from Consul backend to Vault integrated storage

Vault
1

Hi there.
I have a question in Vault storage regard. So we currently have our Vault HA cluster with Consul backend (2 Vault nodes and 3 Consul nodes). And we decided to move to integrated storage as it is easier to manage. So now we have 2 clusters: 1 prod with Consuls and one stage with integrated storage. The stage one is newly created and currently empty. I need to test data migration from Consul to integrated. So I need to move data from one cluster to another. I will refer this, I suppose https://learn.hashicorp.com/tutorials/vault/raft-migration#backup-vault-data.
Will the data be just copied from Consuls to Integrated and i will have two identical storages or it will be moved to integrated and removed from Consuls afterwards?
The vault versions are different.

New cluster with integ. storage: 1.5.3
Old cluster with Consul backend: 1.2.3

Could you please help me with this?

Regards,
Vladyslava

Did you try to enable replication between both and cut replication after copy is done?

Hello,

Regarding this :

Will the data be just copied from Consuls to Integrated and i will have two identical storages or it will be moved to integrated and removed from Consuls afterwards?
The vault versions are different.

According to the docs :

The source data is not modified, with the exception of a small lock key added during migration.

So, the data in Consul should stay intact and the data should be identical between Raft and Consul storages.
