Replication environments rarely remain static. Therefore, best practice is to perform regular switches to ensure that you are prepared should you need to perform one during an emergency.
The Last switch field indicates compliance with best practices. The status of the field is highlighted to indicate the following:
- Yellow - The number of days since the last switch is at the limit of what is considered to be best practice. This threshold is determined by the Switch warning threshold policy.
- Red - The number of days since the last switch is beyond what is considered to be best practice. This threshold is determined by the Switch action threshold policy.
