Merge data from different Nodes

Hi I would like to ask if I can merge two Nodes and their data, operating at different locations to one Node to share the data and operate at one location. Now I need to move second node to the same location as first one, so they are under one static IP.

Thank you

You can run multiple nodes from one location, one IP, even on the same machine. But you need different ports.
You cannot merge the stored data into a single node though.
