Planning to upgrade NSX-T 3.0 to 3.1.3
For Host Transport Node Upgrade - which mode is recommend for Production Environment
1. Maintenance mode or 2. In-place mode
please suggest which is better method for production environment and what is the major difference
Hi,
Before you place your ESXi host in maintenance mode, power off any NSX Edge VMs that may be residing on the host and ensure that the NSX Edge VMs continue to reside on the same host
For ESXi host, for an in-place upgrade you do not need to power off the tenant VMs and placing a host into maintenance mode
before the upgrade
Limitations on In-Place Upgrade
For NSX-T Data Center, in-place upgrade of a host is not supported in the following scenarios:
More than one N-VDS switch is configured on the host.
More than 100 vNICs are configured on the host N-VDS switch.
ENS is configured on the host N-VDS switch.
CPU use for the hostd, nsxa, or the config-agent service is high.
vSAN(with LACP) is configured on the host N-VDS switch.
Layer 7 firewall rules or Identity Firewall rules are enabled.
VMkernel interface is configured on the overlay network.
