I have my nuget packages hosted on a file share, after using TeamCity I enabled the built-in nuget feed. Now comes the question, how I can migrate my old packages from file share to TeamCity so I can decommission the file share and just use the TeamCity instead?
If you are looking to expose 3rd party NuGet packages, you'll need to explicitly publish them as build artifacts. If you are performing a NuGet install prior to compiling your solution then the directory these are restored to should be used as the build artifacts path
e.g.
work\234hkj568rt34jk\packages\** =>
Once you've done this you'll be able to consume them from the NuGet feed by adding this as a package source inside Visual Studio
If it's just internal packages then you just need to run the build configurations and they will be exposed.
