you have to update the wallet [v1.1] {can be found in the discord group on a channel named 'New wallet'}, unlock the old transaction (the one with 5k) , then make a new transaction to yourself for the new Node (25k) and do the same steps like you did before , also you have to update the daemon + cli in the vps side , easiest way would be to reinstall the VPS and then run the script for installing the node again.

For faster communication i advice on asking your questions on the discord group in the MN channel
