Migrating between different blockchain protocols
Interoperability is not currently available on the protocols supported by Chainstack, so you will be unable to migrate data from a ledger running one protocol to ledger running a different protocol.
Migrating between nodes of one blockchain protocol
You can easily migrate data to new nodes on various cloud providers or on-premises.
To migrate, select where you would like to deploy an additional node. Once the node is deployed and synchronizes with the rest of your network, it will have a full copy of the ledger. If required, assign the new node on-chain permissions, and then you can remove your original nodes from the network.
