How to put two servers couchbase

Thank you for the tips. Unfortunately, we are a small company that starts a big project. We are planning another physical servers couchbase. Unfortunately, finances do not allow simultaneous buy some servers are. For now we started with two plans are another. I mean how off without losing data.

I did so and worked with a control panel to manage servers (web)

  1. The main server was turned on
  2. On the server pushed the number 2 key FailOver
  3. I turned off the server 2 added RAM and again turned it on.
  4. I hit the key rebalancer (waited to synchronize data)
  5. On the server pushed the number 1 key FailOver
  6. turned off the server 1 added RAM and again turned it on.
  7. I hit the key rebalancer (waited to synchronize data)

Developers said that data and transactions are all. What I meant is that you can do.
