I understand there might not be a direct answer for this. Some suggestion would be very helpful.
I would like to upgrade from my current elasticsearch version 1.3.4 to some version above 1.7 or 1.7 itself. I would like to use the features like delayed timeout and synced flush.
But I am not sure which is the comaptible version [with minimal changes]. Could someone help me with this?
create a test environment and try to emulate your production environment, including deployment, configuration, data load, and all client interaction, to see if you get broken or unexpected behavior
Thanks for the suggestion Glen. I went through the breaking changes and and decided to upgrade to 1.7. Because 2.0 doesn't have facets which we use mainly in our app.
