Other Important Checklist Items and Notable Mentions

Other Important Checklist Items and Notable Mentions

Verify that port 22 is open on the appliance that you want to upgrade. The upgrade process establishes an inbound SSH connection to download

the exported data from source appliance

Verify that port 443 is open on the source ESXi host on which the appliance that you want to upgrade resides. The upgrade process establishes

an HTTPS connection to the source ESXi host to verify that the source appliance is ready for an upgrade and to set up an SSH connection

between the new and the existing appliance

Verify that the current vSphere and ESXi versions are compatible. See the VMware Interoperability Matrix at

https://partnerweb.vmware.com/comp_guide2/sim/interop_matrix.php#interop&93=&2=&1=

Verify that you have sufficient free disk space on the appliance that you want to upgrade so that you can accommodate the data for the upgrade

Create a snapshot or better yet, take a backup of the appliance that you want to upgrade as a precaution in case of failure during the upgrade process

If you use an external database, determine the database size and the minimum storage size for the new appliance

If you plan to assign a DHCP IPv4 address in the temporary network settings of the new appliance, verify that the ESXi host on which you want to deploy the new appliance is connected to at least one network that is associated with a port group which accepts MAC address changes. Consider the default security policy of a distributed virtual switch, which is to reject MAC address changes

Customer has firewall rule to block new temp IP communicate with it DNS server. During the upgrade, the new temp VC vm has to use the temp IP for the migration. The new temp VC couldn't resolve the host name via its DNS because of DNS firewall rule.
