As provided by development the following SQL queries can be used to delete unwanted MCS templates from the MCS tables in the UIM database:
declare @PROBE varchar(20);
set @PROBE = 'probename';
declare @VERSION varchar(20);
set @VERSION = 'x.xx';
delete from SSRV2PackageTemplate where template in (select templateid from ssrv2template where probe = @PROBE and version=@VERSION);
delete from ssrv2container where template in (select templateid from ssrv2template where probe = @PROBE and version=@VERSION);
delete from ssrv2removal where template in (select templateid from ssrv2template where probe = @PROBE and version=@VERSION);
delete from ssrv2configvalue where field in (select id from ssrv2field where template in (select templateid from ssrv2template where probe = @PROBE and version=@VERSION));
delete from ssrv2field where template in (select templateid from ssrv2template where probe = @PROBE and version=@VERSION);
delete from ssrv2profile where template in (select templateid from ssrv2template where probe = @PROBE and version=@VERSION);
delete from ssrv2template where templateid in (select templateid from ssrv2template where probe = @PROBE and version=@VERSION);
