How does the vCenter deployed by you get a temporary IP address? Keep in mind that if you are not using DHCP then manually you need to assign a free address (after the setup is complete, this temporary address will be freed and the new vCenter will accept the address of the previous one).
>>How does the vCenter deployed by you get a temporary IP address?
Try setting a different address
Why i should use different address? VCSA 6.7 successfully obtains a temporary address.
Any IP Address assigned to vCenter servers, should be a unique IP.
It should not be assigned to any other system.
Since the upgrade path requires a Temporary IP.
Make sure the temporary IP's obtained is unused in the environment.
If the IP Address which is being option is having a duplicate entry, then the upgrade would not complete as the installer would not be able to communicate to the machine once deployed.
temporary IP is free and is unique
As per the error that you have received, it happens because of a IP Conflict.
Either you could use a different IP Address or You could try to track the IP Address using the Article below.
I have this exact problem.
The so called 'conflicting' IPv4 address is that of the OLD VCSA. No way it could be conflicting, since during the installation the old VCSA is shut down.
I tried all kinds of things, even logging in to the NEW VCSA, cleaning the ARP-cache, manually trying to bring up the new IP address, which succeeds, but the installation won't proceed.
I'm pulling my hair out and am thinking of skipping the whole update program since it seems to be just broken.
Downloaded the logs; the installer tries to check for conflicting IPv4 addresses with ARP or so it seems. In the cache my OLD VCSA is found:
vcsa.mydomain (a.b.c.d) at <incomplete> on eth0
Needless to say; my OLD VCSA will always have the 'conflicting' IPv4 address.
Please, can someone help me out?
Update: I logged in to the OLD VCSA on port 5480 and it seems there was an update available for VCSA. Now updating from:
22.214.171.12400 Build Number 7515524
126.96.36.19900 Build Number 8815520
Will try the upgrade to 6.7.0a after that.
Update: Exactly the same. Upgrade seems to be just broken.
Update: 6.7.0b gives the same results.
Could someone please help me out here?
I had this exact same issue last night. On my first attempt I set a static IP for the temporary vCSA and I got this error. The second upgrade attempt I let DHCP handle it and it was successful. No idea why it would matter, but nevertheless, this was my experience.
Just ran into this issue as well, seems like a bug for sure.
Old VCSA is offline, cannot ping it, does not show up in MAC table. Funny thing is when I SSH'd into the temporary DHCP address of the 6.7 upgrade partially failed box and rebooted it via CLI, it actually came up with the correct static address of the old 6.5 VCSA but was inoperable because the upgrade/migration process died.
Will just do it again... maybe I'll get lucky.
QC seems like a thing of the past unfortunately.
I'm having the same problem, have a case open with support. Seems like the old windows vcenter isn't shutting down fast enough before the migration process tries to transfer the IP address. Any ideas on how to delay the IP migration?
Oddly enough, I ran the exact same process again as the first time and it was successful the second. I wish I had a better answer than that... Just for grins I left a continuous ping going during the second migration and it (the old vCenter) shut down well before the new one attempted to start up.
If I remember correctly, I did login to our core switch and clear the ARP cache once the old machine powered down, just in case it was an ARP timeout issue was causing the new vCenter to think the IP was still active.
Hopefully they can get it sorted out for you!
This error appears when the source VCSA is still shutting down (holding the IP address) and at the same time the target is setting the network.
VMware identified this bug and the fix is available in 6.7 U1 release.
Please consider marking this answer as "correct" or "helpful" if you think your questions have been answered. Thank you.
I updated my VCSA from 6.5 to 6.7 as fallows:
Used the 6.7.0d (Release Date: 14.08.2018) binaries.
1. Deploy 6.7 Appliance with the installer using "Upgrade" (Stage 1) and give temporary IP
2. Take Snapshot of the source VCSA and the newly deployed and clean VCSA 6.7
3. Initiate Stage 2 of the Upgrade
- if the installer was closed you can continue by navigating to the Appliance Management Interface of the new VCSA https://[IP OF NEW VCSA]:5480/
4. Wait until the data of the source VCSA is exportet
5. At the step "Shutting down source appliance" connect to the source appliance via console direct on the ESXi Host and force power off
6. The wizard continues and successfully upgraded to 6.7 in my case
