Hi Artur. Not at the moment, no. We will see some improvements early next year that will reduce initial index builds. But we will always need to do rebuild indexes. However, we are also going to allow the backup/restore of Atlas search indexes using the existing Atlas backup/restore functionality. Depending on the specifics of the migration, it may be possible to use this to accelerate restoring indexes. This is something we are currently investigating so we wouldn’t see it in the short to medium term.
