Hi,
I need to migrate indices of 58 GB data from 1.x to 2.x Elasticsearch version but this migration is taking huge time, almost 2 days. It is not feasible for a production environment to shutdown for 2 days for data migration.
Please help me to find-out a way so that migration can be done as well as production system need not to keep shutdown.
Please validate my thinking below.
- Continue with the migration from 1.x to 2.x with a separate instance of 2.x node.
- Change the production system Elasticsearch to 2.x version (a separate node than step 1)
- When the migration got completed then migrated Elsaticsearch 2.x node will be included in the production Elasticsearch cluster.
Regards,
