 Upgrade and replace the restored ledger state snapshot to 'LMDB' flavor by running the command:
 
-    mithril-client --unstable tools utxo-hd snapshot-converter --db-directory db --cardano-node-version 10.5.1 --utxo-hd-flavor LMDB --commit
+    mithril-client tools utxo-hd snapshot-converter --db-directory db --cardano-node-version 10.5.1 --utxo-hd-flavor LMDB --commit
 
     Or to 'Legacy' flavor by running the command:
 
-    mithril-client --unstable tools utxo-hd snapshot-converter --db-directory db --cardano-node-version 10.5.1 --utxo-hd-flavor Legacy --commit
+    mithril-client tools utxo-hd snapshot-converter --db-directory db --cardano-node-version 10.5.1 --utxo-hd-flavor Legacy --commit
 ```
 
 ### Step 5 (optional): Convert the ledger state snapshot to another flavor
 
 After restoring a snapshot with the `--include-ancillary` option, the ledger state is in the `InMemory` format. You can convert it to another UTxO-HD flavor (e.g., `LMDB` or `Legacy`) using the Mithril client `tools utxo-hd snapshot-converter` command.
 
-To do so, run the following command with the `--unstable` flag:

+mithril-client tools utxo-hd snapshot-converter --db-directory db --cardano-node-version latest --utxo-hd-flavor LMDB

 Or, to convert it to the `Legacy` flavor:

+mithril-client tools utxo-hd snapshot-converter --db-directory db --cardano-node-version latest --utxo-hd-flavor Legacy
 ```
 
 Use the `--commit` option to replace the current ledger state with the converted snapshot.
