Hello,
we strongly advise against such a downgrade to be honest. It's potentially very tricky and will very likely mean data loss. Please be aware though that you might need to "downgrade" any Remote Probes manually again, by downloading the Remote Probe installer then from your very own PRTG after the "downgrade to 9", because version 12 that you are currently running is of course newer than the 9 (so Probes will not automatically downgrade themselves). Furthermore, if you added any sensors that are only available with the version 12 (but not in 9), those will not work any more after the switch back to 9. And in case you are running the cluster, that would make things much more complicated I'm afraid. It would be necessary then to:
best regards
