**Excuse me , when I run ES 5.0 with the same data path of ES-2.1.0 (new data path works well ), error occurs :**

"operations are blocked on license expiration. All data operations (read and write) continue to work.  
If you have a new license, please update it. Otherwise, please reach out to your support contact.  
[2016-11-10T17:50:35,886][ERROR][o.e.x.s.a.f.SecurityActionFilter] [xxx] blocking [cluster:monitor/health] operation due to expired license. Cluster health, cluster stats and indices stats"

**how should I use the old data with the new version ?**  
**what is the bast practice to upgrade ES with so much data , and even there were some deprecated mapping struct**  
looking forward to your reply

That's a licensing issue, not a compatibility one.
