Several customers reported that child primary sites were entering maintenance mode after upgrading the central administration site from System Center 2012 Configuration Manager Service Pack 1 (SP1) with CU2 or CU3 to System Center 2012 R2 Configuration Manager. Entries similar to the following were recorded in the RcmCtrl.log file at child primary sites:
ERROR: Exception message: [A .NET Framework error occurred during execution of user-defined routine or aggregate "spModifyGlobalTable": ~~System.Data.SqlClient.SqlException: ALTER TABLE only allows columns to be added that can contain nulls, or have a DEFAULT definition specified, or the column being added is an identity or timestamp column, or alternatively if none of the previous conditions are satisfied the table must be empty to allow addition of this column.

This error occurs because the PullDPResponse table, which was added with Configuration Manager SP1 with CU2 or CU3, does not contain the MessageTime column that was later introduced with System Center 2012 R2 Configuration Manager. This column did not allow for NULL entries, and therefore, replication would fail if there was data in the table at the Configuration Manager 2012 SP1 child site prior to the upgrade. When an update was started on the child site, the Prerequisite Checker failed because replication between the central administration site and child primary site was not active.
This issue has been resolved for all new System Center 2012 R2 Configuration Manager upgrades as of November 14, 2013. New installations or upgrades will download updated setup prerequisite files.
Existing hierarchies that have already upgraded the central administration site but cannot upgrade child primary site(s) can be repaired by running the following SQL script against the site database at the child primary site(s):
IF NOT EXISTS(select * from sys.columns where [name] = N''MessageTime'' and [object_id] = OBJECT_ID(N''PullDPResponse''))
ALTER TABLE PullDPResponse ADD MessageTime datetime NOT NULL
