Migrate Sharepoint 2010 with TFS 2010 Inetgreated to Sharepoint 2013 and TFS 2013.

Hi,

Currently we have SharePoint 2010 and TFS 2010 , both are installed on two different 2008 servers

TFS 2010 is integrated with SharePoint 2010 using TFS extension pack,

Now, we are planning to Upgrade\Migrate TFS and SharePoint 2010 to 2013.

What will be the correct order to migrate, i.e. first migrate TFS or SharePoint or vice versa.

Any steps ?

Thanks in advance
