Migrating Data Center

To migrate to a new data center, first add the new data center to your configuration and set the Traffic % value of the old data center to 0%.

For example, if you have an ALB setup with Load Balancer with a single data center (DC1).

Data Center	Traffic %
DC1	100

To switch to another data center (DC2):

Create a new version of Load Balancer with the following configuration:

Data Center	Traffic %
DC1	0
DC2	100

Activate this configuration.
Remove DC1.

Data Center	Traffic %
DC2	100

Activate setup with DC2 only.

You have successfully migrated to a new data center.

If you may want to switch back to DC1 in the future, you can skip steps 3 and 4. Leave the Load Balancer configuration active which has DC1 at 0% and DC2 at 100%, so that you can easily switch back to DC1 by adjusting the Traffic %.
