Waiting is an option however I presume in coding of changes are made to the FW code can effect any of the options recorded in previous version of configuration files, applying any older configuration files on to newer loaded FW version can and will present problems and the configuration options may no longer be available in the new FW version. This is why I've stressed that doing factory resets before and after FW updates and not loading saved configuration files is best. I have noticed that even on the 857, going from 1.00, 1.01 and 1.02, there was an odd behavior of my saved configuration files not working or not loading on to v1.01 for some reason. Even after a factory reset. I reported it to DLink and since then v1.02 was released. Ya I had to start from scratch. I wish they could nail down using configuration files better in line with FW updates. So waiting for newer firmware in hopes of using old configuration files, remember this, what they might take out of FW will probably effect old configuration files and usually what they take out is not put back in. This may have been a case here with the 827.
However Patrick, in your case, if it's working, don't fix it!

I think when the time comes that you need to upgrade FW, I would take screen captures of all the current options you have configured and save them for later use and you can test it out. Upgrade FW and see how it does. If it seems stable, then save off another configuration to file. If it doesn't seems stable, save off to file, factory reset and set up from scratch.
I have a few captures for what I need and have them printed out. Especially for IP reservations.
