Adding upgraded Host to existing Data center cluster

Upgraded an existing ESXi host hardware.  Moved to a server that is one generation newer.
Old Host Name - HQESX02
Old Host IP - 192.168.100.XYZ
Old Host Gateway -

Just moved the thumb drive from the old server to the new server.  Server booted just fine, no errors.  Host name, IP and Gateway were not changed.

Logged into the Web Client and the Host (New Server) with the existing host information showed disconnected.  Tired to reconnect and got an error that said "Cannot contact the specified host (HQESX02.domain.com).  The host may not be available on the network, a network configuration problem may exist or the management services on this host may not be responding."

When connecting the new hardware, I simply plugged all the network cables back into the same nic ports on the back of the server.

I reviewed a KB article that suggested that I remove the host from inventory and re-add.  I was able to successfully remove the host, but when I try to re-add the host I get the same error message.

Not sure what to try next???

Merry Christmas Scott!

When logged onto the vCenter Server, can you resolve the HOST - HQESX02.domain.com ?

by IP Address and FQDN ?

it appears there is a communication issue between Host and vCenter Server ?

can you ping the host ?

(moving flash drive from one host to another host IS NOT SUPPORTED!) - it may appear to operate!

The supported method is to re-install the OS, available from Server Vendor onto the Host!

This could be a MAC Address, or network interface re-configuration issues.

So can you ping HQESX02 ?

can you ping HQESX02.domain.com ?

can you tracert to HQESX02 ?

can you tracert to HQESX02.domain.com ?
