ISC supported customers should be looking into the use of ISC CCR (ChangeControlRecord) as well as SystemDefaultSettings. CCR is powered by Perforce and handles the transport of config and code between environments. It features in its latest version Production decomposition which transports only the actual changed code/config and no longer the complete production definition.

Hi,

the question here is why do you want to disable ChangeControl hooks?
For localised changes you should look into using using SystemDefaultSettings. I can see the reasoning to disable the hooks on the Production page, but even that should only be done for a short period and not in general.
 

Just to mention there is another option to storing large JSON objects. You could use DocDB for unstructured JSON objects i.e. if the JSON structure is unknown. Or, my preference, if the structure is well known, you could use %JSONAdaptor to map a Storage class to the same values in your json string and then just import the json, ending up with an IRIS Persistent object.
