When you upgrade from Release Management for Microsoft Visual Studio 2013 Update 1 to Release Management for Visual Studio 2013 Update 2, Team Foundation Server builds are not displayed in the Release Management template.
To work around this issue, validate the following when you upgrade Release Management:
Release Management configuration has to be done again during the upgrade.
HTTP or HTTPS protocol is the same across the server, client, and deployer after the upgrade.
If the protocol is changed from HTTPS to HTTP during reconfiguration, then manual reconfiguration is required for the Release Management server, client, and deployer.
