Re: [protobuf] Message Migration Practice?

['Josh Haberman' via Protocol Buffers]

If the structure of the schema changes, your new schema will be 
incompatible with your old schema. You might need to convert the data 
manually to your new schema in this case.

How to migrate when the schema structure change?
I'm talking about fields moving of a schema of a serialization file that 
needs to be migrated.

[protobuf] Message Migration Practice?

[Minhyuk Kwon]

Hello,

I have plan for introducing protobuf to in our products for passing 
information of product's input project file structure.
And this information may frequently upgrade near future(via product version 
upgrade).

So, I have a question. 
If I remove old field from message and add new field, Can I (auto)migrate 
without breaking change?
And if you guys have(or know) document for this kind practice, please let 
me know.


Regards,

-Kwon
