Server migration, build template tries to be obtained from old server

Question

I migrated our organisations instance of TFS, new install on a new server and migrated the database over to the new environment, all went well and were now using the new server and source control/tasks are working as expected, however, the builds on the
other hand have not.
Reference: Old server srv-systest:8080/tfs new server srv-tfs:8080/tfs
I created a new build server on the new TSF server and some agents and set up new build definitions however, whenever a build runs, it errors with this:
Other Errors and Warnings
1 error(s), 0 warning(s)
TF215097: An error occurred while initializing a build for build definition \EServices\Unit test - Continous Integration:

Details 503:Service Unavailable - TF24668: The following team project collection is stopped: Development. Start the collection and then try again. Administrator Reason: Migrated to http://srv-tfs:8080/tfs - Any questions see Andy Jones (type FileNotFoundException)

I have deleted the build agents, recreated then and checked the templates however, I cannot see anywhere, the setting to say where to get the template from.
Any ideas?

Hi CRABAPPLES, 
Thanks for your post.
What’s the versions of your two TFS Servers, both are TFS 2013 Update 4?
How did you migrated old TFS database to the new installed TFS Server? (if have installed the new TFS Server, and want move collections from old TFS Server to new TFS Server, you should Detach collection in old TFS Server, then backup collection databases
from old TFS SQL Server, and restore to new TFS SQL Server, then Attach the collection databases in new TFS Admin Console)
This Development collection is your old TFS Server collection? Not migrated to new TFS Server?
In your current new build definition>>Process tab, selected the
Default Template in Build process file dropdown list, then click
Download, the default TfvcTemplate.12.xaml can be downloaded successfully? If yes, we suggest you manually create a
BuildProcessTemplates folder in your current team project Source Control, and add/check-in this downloaded TfvcTemplate.12.xaml build template into this
BuildProcessTemplates folder, then in build definition>>Process tab, in
Build process template section, click New… button to add this TfvcTemplate.12.xaml from your team project>>
BuildProcessTemplates folder, then save build definition and queue it again.
