You probably want to take a look at aliases -

Hi,

If index name need to be changed, the provided link states that it should be reindexed. If possible can you let me know, how to do re-indexing, what exactly mean of reindexing.

Please let me also know, If I am wrong here.

Thanks & Regards,
Akram.

It means index again your documents from your source (or from elasticsearch) in another index.

What is unclear?
