 To get an idea of the downtime required for migrating your server, we strongly recommend taking a **PITR (point in time restore)** of your single server and running it against the single to flex migration tool. Monitoring the **PITR** migration gives a good estimate of the required downtime. Additionally, if Read replicas (RR) or High Availability (HA) is used, they should be enabled or provisioned **after** the migration is complete. When the migration starts, there's a lot of data copied to the target. If HA or RR is enabled, every transaction has to be acknowledged and it increases the lag between the primary and the backups. The lag in turn impacts cost in terms of extra storage and time required to complete the migration and hence should be avoided. This precaution ensures that the migration process completes seamlessly.
