I have a quick question before we move forward with the migration of our appliance. hopefully someone can help us out!
it looks like during the migration process, you select a name for the new vcenter appliance.
so when we upgrade, will the fqdn change?
After the upgrade will have a new fqdn of
if so, we will need to make some firewall changes to accommodate the new appliance name.
as well as request new certificates
Thanks in advance!
The installer deploys an empty instance of the new vCenter with a new temporary IP address and does a data migration that imports all the configuration data into the new appliance.
The upgrade will maintain the original FQDN name of the VCSA. The name that you specify in "set up target appliance vm" windows will be used as VM name in the VCSA inventory and can be changed later.
Prior to migration, rename your vcenter appliance VM to _old or any other name.
Regarding the FQDN and firewall changes, nothing is needed.
All the temporary names, IP address mentioned are used for data transfer purpose from old vcenter to new vcenter only.
It will retain your vCenter FQDN to new vcenter server.

This upgrade process has two stages with multiple steps in each stage:
