Upgrading Considerations - Windows Server Version

1. Do you need or want to upgrade to a newer Windows Server version?

If yes:

  • Not recommended: In-place upgrade of Windows Server, followed by in-place upgrade of K2. Only consider this with careful backups and testing.
  • Recommended: Set up a new Windows Server. This involves:
    • Backing up the database
    • Installing K2 on the new server
    • Preserving the option to roll back to the old server if needed

2. Is your K2 setup standalone or a farm?

If standalone:

  • Using hostname for K2 site binding: This requires the most migration work, especially with a new server hostname. Consider reconfiguring to a farm setup for easier future migrations.
    • New server with same hostname: Less manual updates needed.
    • New server with different hostname: More manual reconfigurations required, including SharePoint integrations.
  • Using DNS for K2 site binding: Migration is simpler. Consider reconfiguring to a farm setup for future benefits.

If farm setup:

  • Using DNS for K2 site binding: This is the simplest migration scenario. The farm DNS handles server changes seamlessly. DNS can point to a single server or a load balancer for flexibility.

If you don't need to upgrade Windows Server:

  • Perform an in-place upgrade of K2 on the same server.
  • Take a database backup and VM snapshot for rollback options if necessary.
