Getting error "Object Reference not set to an instance of object". on the screen 'Migration Project(s)'. Select Team Project(s) does not fill in projects for migration. I am overall TFS administrator and have full access. Migration we are doing is from TFS 2010 to VSTS. we are using free version. Please let me know what needs to be done to fix the issue.
Checked whether all components needed are installed and they are installed (TFS Object Model 2012 and Dot Net framework 4.0)
Carried out the Proxy settings too.
Advised to post this here.
Originally tried to post on OpsHub TFS to VSTS migration - Object reference not set to an object exception but not allowed.
The solution provided there did not work. I am a Project Collection Administrator on the VSTS side and an Admin on the TFS side.
The version is V2.8.1.000
