Behavior of masterkey on rSeries

Is there any difference in regards to the usage of the masterkey on rSeries? I mean is this still different/dedicated for the F5OS and all the tenants? Or is there just ONE masterkey, which needs to...

    Dear Jeffrey,
    thank you for the quick answer!
    My BigDB.dat file doesn't contain an encrypted value in the section [Configsync.password] at all, so I don't followed they other steps.
    I then realized that on the second tenant of the HA-cluster the load sys config command works fine without any issues.
    And finally the root cause on the primary tenant was somehow related to a time sync problem. I noticed that NTP was not working correctly due to wrong/mistyped NTP-servers (DNS-names).
    Once corrected the load sys config command was working fine on this tenant as well. Do you maybe have an explanation for this behavior?

    Finally we can summarize: there is NO special behavior for the masterkey on rSeries. As already mentioned in this F5 article replacing the masterkey with the f5mku command is sufficient.

    Thank you anyway!

    Regards,
    Stefan
