Hello,

Could you please help me to solve this issue ASAP? Our QA and staging 
environments encounter this error "message OakOak0001: Command failed with 
error 10334 (BSONObjectTooLarge): 'BSONObj size: 16848200 (0x1011548) is 
invalid. Size must be between 0 and 16793600(16MB) First element: _id: 
\"1:/channels\""  .

We are very worried about this error will occur in the production environment.

Since we used "nt:unstructured" as JCR primary type of node /channels, and the 
value of property ":childOrder" is larger, almost 16M .

There are 2092 channels in our db, one line of property ":childOrder" about 
800kb.

Could you please tell me how to reduce the existed  property ":childOrder" 
value, and how to convert existed date from "nt:unstructured" to 
"oak:unstructured"?  Do you have reference about it?

For more background, please refer to OAK-9620.
