Versions (relevant - OpenSearch/Dashboard/Server OS/Browser): AWS Opensearch managed v7.4
Describe the issue:
I would like to migrate from AWS elasticsearch 7.4 to AWS opensearch v2
From what I understand, I can go from
option 1) reindex from source to destination V1 and then go to V2
option 2) directly from dynamodb data source to V2
option 3) from snapshot restore to v1 and then go to v2
My questions are
Question 1
-
if option 1) when reindex, do this cause performance issue to existing cluster?
-
if option 1) reindex, do I able to jump from 7.4 to v2 by ensuring the fields compatible? Or I can only jump from 7.4 → v1 → v2 path
-
if option 2, there will be no issue since will ensure all compatible before index into new v2 cluster
Question 2
if option 3, snapshot was able to go to v1 as tested but still need reindex to go from v1 to v2?
Question 3
What would you suggestion with path to go with less cost and short time?
Configuration:
AWS opensearch managed cluster
