To perform a migration it is important to take into account the size of the environments to be migrated and the amount of indexes and documents we have stored. Migration is a demanding process that transfers a lot of data at high speed.

In general we indicate certain recommendations for environments with a large amount of data:

  • Perform the migration before connecting the pandorafms environment to the new opensearch.
  • Perform a staggered migration, year by year, month by month or even index by index, using the pattern filter. Depending on the amount of data stored.
  • Right-size the environment.
  • For a large amount of data, use an opensearch cluster instead of a single node.
