Upgrading from Lucene to Elastic search indexing


We are currently in Pega 7.1.7 version with 2 batch nodes and 4 user nodes. We have disabled the elastic indexing and running the legacy lucene indexing to a shared mount.

We have customised the search so that all nodes can search the indexes from the shared mount.

Now we are upgrading to Pega 7.1.9 and would like to update to Elastic search indexing.

We have few concerns that needs to be addressed:

Since we have around 2 million work objects and our system needs to run 12 hours 7 days a week with outage of only 8 hours we are looking for options on how to re-index

Option 1:- Run the re-indexing through one of the batch node. Please confirm if it is for the re-indexing to run during the business hours when users are on the system.
Option 2:- Initiate the re-indexing through batch from some local desktop connected to production database with increasing the number of threads. But not sure whether this can go during the business hours when users are on the system. Please confirm.

In option 1 we can increase maxnumworkers setting to 10 and run it as well.

Please let us know if there is a better way in doing this.
