Two node upgrade process

The idea is to set up a new two node system and to keep the current two node system as a backup.

1. Install a new two node system. During installation:
   1. Transfer configuration files from old two node system from corresponding nodes to the new two node system.
      • the whole custom folder
      • linux.config

      • Do this by running from old master node:

        scp /usr/local/ubisecure/customerid/application/linux.config <new_master_node_user>@<new_master_node>:
        scp -r /usr/local/ubisecure/customerid/application/custom <new_master_node_user>@<new_master_node>:

      • Then on new master node, run:

        mv /home/<new_master_node_user>/custom /usr/local/ubisecure/customerid/application/
        chown -R wildfly. /usr/local/ubisecure/customerid/application/custom
        chmod 644 /usr/local/ubisecure/customerid/application/custom/jndi.properties

   2. Correct properties included in the linux.config file.

   3. Execute setup script on both nodes:

      cd /usr/local/ubisecure/customerid/application
      ./setup.sh

   4. Perform database schema update depending on versions.

      • See Database Changes.

   5. Point the new installation to the same data storages that the old two node system used.
2. Move traffic to the new two node installation.
3. Shutdown old two node system.
4. Backup and remove old two node system.
