Teamcity upgrade - Nuget feed question

We are planning on upgrading from 2017.1.4 to 2018.2.2.  Reading through the release notes, we noticed the nuget feed change from the server level to project level.

The change we are concerned with is:

• The enabled default NuGet feed with all published packages accessed by URL /app/nuget/v1/FeedService.svc/ is now moved to the Root project feed /app/nuget/feed/_Root/default/v2/. It is recommended to switch to new URL in your projects.

Will the original URL still work?  We utilize chocolatey in our company, and we have that feed configured as a source on many hosts.
