Hi Alena and welcome !
Are you “confortable” with the console?
If yes, here’s a way :
Connect of your AWS node and go into your node directory. You can use the following command :
cd "$(find / -type d -name "nkn-node" 2>/dev/null)"
In the directory are 2 files :
Those are the file you need to save for now.
Once those files saved, head to DO and setup your new nodes (I think you can use their installer, otherwise the All-in-One script is really easy to use)
Once your new nodes started they should be asking to pay generation fee (you can see that checking their IP on nstatus.org). Don’t pay them.
Connect to your node in ssh and go into your node directory using the same command as on your old nodes.
Delete the existing
wallet.pswd files, replace them by the ones saved from AWS.
At this point it is really important to shutdown your AWS nodes.
You can’t run 2 nodes with the same wallet.
Once your old nodes are shut down restart your new nodes.
You should be using your AWS generated IDs on DO
