Hi Team,

We are using the ES version as 7.3.2 for our environment.

Now we are planning to upgrade our elasticsearch to 7.17.3.

May i know is there any search speed or indexing speed will increase after upgrade?

Hi @Siva_Karan

There are many many enhancements (to numerous to list) from 7.3 to 7.17 so I would expect some improvements BUT the only way to be sure is to test! 🙂

Also, you should upgrade to the latest 7.17.15.

You would probably need to go though the release notes for each release. The release you are using is over 4 years old and has been EOL for a long time, so the release notes will cover a good amount of development.
