Deploy nodes between blocks 2570000 and 2600000

Can I still deploying nodes between 2570000 and 2600000 or do I have to pay the 10 NKN fee?

I want to remove or migrate some nodes with low performance to other zones or servers, they are currently running version 2.1.1.

  • Do I have to close them and implement them again or can I migrate them?
  • If that were the case, how would I have to migrate them without losing the ID?
  • Does de ID depends on the IP?
