Trying to upgrade a solo system to 884-9095. It is failing upgrading the compute group at this step:

> EntryRecordSet CREATE\_FAILED [RRSet of type A with DNS name [entry.datomic.us-west-2.datomic.net](http://entry.datomic.us-west-2.datomic.net/). is not permitted because a conflicting RRSet of type CNAME with the same DNS name already exists in zone [datomic.us-west-2.datomic.net](http://datomic.us-west-2.datomic.net/).]

I am wondering if this is connected the new endpoint changes? My system name is “Datomic” (yes, not great), does this need to be a unique name given that it appears it is trying to create a DNS record based on this name in the AWS region?

Hi, have you made progress on your upgrade?

As for your issue, yes, it’s [not recommended](https://docs.datomic.com/cloud/operation/new-system.html#naming) to name your system “Datomic”.

Yes, thanks for the follow-up. I was able to resolve the issue by deleting the compute instance and re-installing. It is now up and running great.

As for naming it “Datomic” I unfortunately read the section you referenced after already starting the install. It is working fine but does make understanding the names a bit more confusing.
