Migrating Windows vCenter Server 5.5 to VCSA 6.5

I followed these instructions: https://esxsi.com/2016/11/17/vcsa65m/

I had run in to an error during stage 2  somewhere around 90%

Error setting network. Details : 16/03/2017 18:13:11 Error running /sbin/ifup command, return code: 1 Unable to set the network parameters Failed to set network

I was able to get my old windows vCenter server 5.5 back and running for now but I would like to return to the migration and move to the virtual appliance.

Any help would be appreciated.

This could be a DNS issue. Can you resolve a vCenter by name and IP? Particularly from the location you are migrating.

Also did you specify any NTP server while you were setting the migration?

1. yes the old windows vcenter server 5.5 resolves correctly. (the new one didn't get installed)
2. there was no option for the NTP server in stage 1 and 2.

From where are you running that migration?? From the vCenter itself?

Are you migrating to a diferente DNS name or IP?

I am running the migration from another server (as instructed by the migration wizard)

No I am not changing DNS or IP.

During the process I have to use temporary IP (I am using IP in the same subnet as the old server and the same DNS server)
I will try to monitor the process this time and I will try to see if the DNS host name will get assigned to the temporary IP)
If not I will try to add it manually.

Yes correct, that is all the right procedure.

Also check the firewall from the source and also in the Windows vCenter that can also be an issue.

But honestly since this in the finish I will point DNS.

The new run succeeded successfully.
Thank you for pointing me to look at the DNS.
The only change I made was point it to a different DNS server in the AD domain and all was good.

thank you for the help!
