Single node to two node upgrade process

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

1. Install a new two node system. During installation:
   1. Transfer configuration files from old single node system to both nodes of the two node system.
      • the whole custom folder
      • win32.config
   2. Correct addresses included in the win32.config file.

   3. Execute setup script on both nodes:

      cd /D "%PROGRAMFILES%\Ubisecure\customerid\application"
      setup.cmd

   4. Perform database schema update depending on versions.
      • See Database Changes.
   5. Point the new installation to the same data storages that the old single node system used.
2. Move traffic to the new two node installation.
3. Shutdown old single node system.
4. Backup and remove old single node system.
