When running DBLoad going from version 12.3.X to 21.X, the following error is present:
'Cannot find the object "MQ1CP006" because it does not exist or you do not have permissions'
Release : 21.X
Component : Automation Engine, DBLoad utility
Since MQ1CP006 is not present in 12.3.X, this error can be ignored. For that, click 'OK', and once the next pop-up shows up, select 'Ignore'.
This error can appear multiple times depending on which version you are upgrading from, and can be safely ignored.
