Be sure and check your config archive to ensure it provides what you want. When we did the same for a 4402 WLC, then config that was archived was essentially the "show run-config" output. This is very different from, and much less complete than, the XML file generated by doing a config backup via the controller's web interface.
Since we use WCS I did not test anything further, but I would urge you to ensure that the archive provides you with the recoverability that you need (or that you know what other pieces you need to ensure the full recovery of a failed/dead controller).
