Hey, migrating a TFS database to VSTS has some ceremony but it works, see Migrate to Visual Studio Team Services[^]. However, you have to upgrade to the latest TFS before doing so. We have done this procedure for a moderate database of 50GB that contained ~10 projects among which was an ASP.NET+WebAPI project, but the contents of the database are of no significance. However, I would suggest that you create fresh projects using git (if you are not using it already) and keep the old ones for archival purposes. Our team was of your size when this operation was carried out :java:. Setting up a CI/CD pipeline is very easy, see Create your first build and release | Microsoft Docs[^] and dotNET Core|Microsoft Docs[^]. For build, we use some hosted agents for small projects and one private agent on a VM for larger native projects. In our case, we had to migrate our xaml based build definitions to the new logic, but this was for the best :) .
