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 another ledger running another protocol.
However, you can easily migrate data to new nodes on various cloud providers or on-premises. Just select where you would like to deploy an additional node. Once that node has been 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 wherever it has been deployed.
