We have a number of remote sites all running a separate instance of EPO 4.0. I've upgraded our main site with EPO 4.5, and I'd like to replace the servers at the remote sites with an agent handler, so that all of our clients are administered from a single server. I've tried this at one site by uninstalling EPO 4.0 and installing the agent handler. The clients won't report to the handler, and I presume that this is something to do with the security keys. I have a backup of the keys from the old server before I uninstalled it, is there somewhere I can poke these in so that I don't have to redeploy the agents?
