Downgrade From From 5.7.2 Tp 5.6.4 Fails

by May 13, 2014



I am doing testing of the 5.6.4 to 5.7.1 upgrade. I have a dev instance of monyog that was a fresh install. I coped over the data from the prod 5.6.4 instance to the dev 5.7.1 instance. It started up just fine. So now I need to test the downgrage path in case we have issues in production with the new version.


When I start up the dev intance with the 5.6.4 binary these are the error message that i get in the logfile. It starts but does not have the 1 server that was monitored in 5.7.1.

How do I do a sucessful downgrade ?
