gateways are upgraded, and their previous instances are decommissioned before
the updates are propagated, then the primary datacenter will become unreachable.
To safely upgrade primary gateways it is preferable to do one of the following:
- Avoid decommissioning primary gateway IP addresses, since the [primary_gateways](/docs/agent/config/config-files#primary_gateways) addresses configured on the secondary

To safely upgrade primary gateways, we recommend that you apply one of the following policies:
- Avoid decommissioning primary gateway IP addresses. This is because the [primary_gateways](/docs/agent/config/config-files#primary_gateways) addresses configured on the secondary servers act as a fallback mechanism for re-establishing connectivity to the primary.
- Verify that addresses of the new mesh gateways in the primary were propagated
to the secondary datacenters before decommissioning the old mesh gateways in the primary.
