Usually re-creating region and index are expensive and customers are reluctant to do it, according to my memory.
We do have an offline reindex scripts or steps (written by Barry?). If that could be an option, they can try that offline tool. I saw from Mario's email, he said: "I didn't found a way to write lucene in older format. They only support reading old format indexes with newer version by using lucene-backward- codec." That's why I think option-1 is not feasible. Option-2 will cause the queue to be filled. But usually customer will hold on, silence or reduce their business throughput when doing rolling upgrade. I wonder if it's a reasonable assumption. Overall, after compared all the 3 options, I still think option-2 is the best bet.
