We are currently running elastic 5.6. We are switching servers and we wanted to take this opportunity to upgrade to elastic 7.
Our original plan was to backup our indexes -> load the backups to elastic 6.8 on the new servers -> use the upgrade asistant to upgrade from 5.6 to 7.
I want to note that our db is large and have many indexes and nodes (few dozens of nodes and indexes).
Would that be ok? Should we maybe instead load the backup to an elastic 5.6 (and not 6.8) on the new servers, and upgrade from there?
