To reconfigure the Operation Center HA pair, complete the following:

1. Log in to the Operation Center CLI as admin.
2. Run the `reset tunserver` command:
  `oc (primary)> reset tunserver`
  `Notice: This operation will clear all Tunnel CA, server, and client`
  `configuration and shut down the Tunnel service.`
  `Continue? (y/n) [n]: y`
  `+++ Stopping OpenVPN Server ... OK`
  `+++ Configuring OpenVPN Service ... OK`
  `+++ Clearing Server Config ...OK`
  `+++ Clearing CA Config ... OK`
  `Launching "failover tunserver reset" on "172.19.2.59"...`
  `The server needs to be restarted for these changes to take effect.`
  `Do you wish to restart the server now? (y/n) [y]: y`
  `+++ Restarting Server ... OK`
3. Run the `configure tunserver` command and configure it with OC VIP address (Server Public Virtual Name or VIP address):
  `oc (primary)> config tunserver`
  `+++ Configuring CA Settings`
  `CA key expiry in days [5475]:`
  `CA key size in bits [2048]:`
  `+++ Configuring Server Settings`
  `Server key expiry in days [5475]:`
  `Server key size in bits [2048]:`
  `Server Public Virtual Name or VIP address [172.19.2.66]: <- By default it will be already oc VIP`
  `Select tunnnel IP protocol. 'udp' recommended for better performance.`
  `Protocol (udp, udp6, tcp) [udp]:`
  `Tunnel network /24 base [169.254.50.0]:`
  `Block cipher:`
  `0. None (RSA auth)`
  `1. Blowfish-CBC`
  `2. AES-128-CBC`
  `3. Triple DES`
  `4. AES-256-CBC`
  `Enter Choice [2]:`
  `Use compression [y]:`
  `Use these settings? (y/n) [n]: y`
  `+++ Initializing CA (may take a minute) ...`
  `+++ Creating Server Params and Keypair ...`
  `Generating DH parameters, 2048 bit long safe prime, generator 2`
  `This is going to take a long time`

As the result, the Operation Center obtained the new server IP address (failover VIP).
