FQDN mismatch issues

[akapinos001]

I'm receiving the following error during upgrade:

The source appliance FQDN VCENTERVDIDEV.AD.XXX.XXX must be the same as the source appliance primary network identifier vcentervdidev.ad.XXX.XXX.

Obviously they appear the same FQDN but one is capitalized while the other isn't. I worked with vmware support to change the PNID to all caps, which seemed to work, but it still gave this error. I have a case open but I'd like to know if anyone here has any ideas on how to manage this error. Thank you for any and all help.

Hi akapinos001,

Hope you are doing well.

Thank you for posting your query.

Regarding the error:
The source appliance FQDN VCENTERVDIDEV.AD.XXX.XXX must be the same as the source appliance primary network identifier vcentervdidev.ad.XXX.XXX

Please follow the below and let me know the outcome:

SSH into source VCSA and make the following changes after non-memory, non-quiesced snapshot of the vCenter VM(and PSC if it is external), before implementing any change.

/opt/vmware/share/vami/vami_config_net changed hostname to vcentervdidev.ad.XXX.XXX
Start Stage 2 of Upgrade

Note: This issue happens for case mismatch for upper & lower case.
