I have a 5.4.1 Elastic cluster that takes snapshots for backup. In case of a disaster (ie. our current cloud provider goes offline) we would need to quickly move to a different cloud provider. I'm looking into moving to AWS in case of such disasters temporarily until the main cloud infrastructure get's back online, in which case I will have to transfer back whatever new data was brought up into the temporary database. Using Elastic cloud I only have the option of picking version 5.4.3 of Elastic, and I know I can't restore a snapshot created with 5.4.1 into a 5.3 cluster (tested with the official AWS Elastic Service). Therefore, I ask:
What would be best way to restore the database from 5.4.3 into my primary 5.4.1 cluster? Should I use a remote re-index feature to merge my temporary databases documents to my permanent database as opposed to using a restore?
