Team Foundation Server 2018 Data is Null

Question

Hi All,

I am trying to configure Team Foundation Server 2018 with SQL server but i am getting an error at readiness check validation " TF255407: An error occurred while attempting to validate the configuration database. Error message: Data is Null. This method or property cannot be called on Null values." I already have TFS setup running on one of the server which is currently live and its working fine. I want to setup one more server to test the backup of TFS data, so for that i have installed same version of TFS i.e. 2018 and SQL server 2016. Below are all the activities which i have performed.

• Running TFS Instance Details.

1. TFS Version: 2018
2. SQL Server: 2016 SP1
3. OS: Windows server 2019
4. TFS DB's:
   1. Tfs_Configuration: 1.5 GB
      1. Tfs_Projects: 48 GB
         1. Tfs_Products: 24 GB
            1. Tfs_AppDevelopment: 29 GB
               1. Tfs_Migration: 7 GB

• New Server Details.

1. TFS Version: 2018
2. SQL Server: 2016 SP1
3. OS: Windows server 2016

All above db backups i have restored on new server. Installed TFS 2018 and when trying to configure i am selecting existing deployment, Please look at the screenshots below.

Answer 1

Since the immediate error comes from TFS, this question cannot be answered from knowledge about SQL Server alone. Thus, you need to find a forum where they disuss Team Foundation Server. I don't know of such a forum, but I'm quite sure that TFS is not covered by Microsoft Q&A.

Devops / TFS is not currently supported here on Q&A. The product group for Azure DevOps / TFS actively monitors questions over at
