if any problem if I use old rocketmq client 3.X and upgrade server to 4.1

Dear All,
      Want to know, can I just upgrade rocketmq server version from 3.4 to 4.1, and let client version keep 3.X. Then I can upgrade client version later.  
      Thanks.

I did the same as you said and succeeded.


Notice that you should upgrade nameserver and broker at the same time.
