I have 2 Elasticsearch clusters i.e with version 7.5.1 and 8.4.3.
I am migrating the data from a lower version to a higher version using ReIndexing with a remote server approach.
- Is there any better solution to do the same?
- Where can I find the benchmark for this Reindexing approach to estimate the data migration time?
Thanks and regards,
I don't think so, reindex from remote is probably the best option, unless you already have snapshots of your indices, then you would need to just restore them in your new cluster.
You won't find, there is none, this depends entirely on the performance of both your clusters.
You should reindex a couple of indices and estimate the time from there.
