Hi There,
Use this below SQL Query and run it in the WarehouseDB to see the existing grooming settings:
select ds.datasetDefaultName AS 'Dataset Name', sda.AggregationTypeId AS 'Agg Type 0=raw, 20=Hourly, 30=Daily', sda.MaxDataAgeDays AS 'Retention Time in Days' 
from dataset ds, StandardDatasetAggregation sda 
WHERE ds.datasetid = sda.datasetid 
ORDER by ds.datasetDefaultName
Example, Mine is 120 days.
So you decide your grooming period and use the below SQL Queries and run it so your grooming setting changes. Just change the Value 120 & 30 & 60 from my query to your Day number which is required.
These were used to groom my warehouse database
-- Alert Data:
USE OperationsManagerDW 
UPDATE StandardDatasetAggregation 
SET MaxDataAgeDays = 120 
WHERE GroomStoredProcedureName = 'AlertGroom'
USE OperationsManagerDW 
UPDATE StandardDatasetAggregation 
SET MaxDataAgeDays = 120 
WHERE GroomStoredProcedureName = 'AemGroom' and AggregationTypeId = '30'
--Event Data: 
USE OperationsManagerDW 
UPDATE StandardDatasetAggregation 
SET MaxDataAgeDays = 30 
WHERE GroomStoredProcedureName = 'EventGroom'
--Microsoft.Exchange.2010.Reports.Dataset.Availability
USE OperationsManagerDW 
UPDATE StandardDatasetAggregation 
SET MaxDataAgeDays = 120 
WHERE GroomStoredProcedureName = 'Exchange2010.AvailabilityGroom'
--Microsoft.Exchange.2010.Reports.Dataset.TenantMapping 
USE OperationsManagerDW 
UPDATE StandardDatasetAggregation 
SET MaxDataAgeDays = 120 
WHERE GroomStoredProcedureName = 'Exchange2010.TenantMappingGroom' and AggregationTypeId = '30'
--Performance Data: 
USE OperationsManagerDW 
UPDATE StandardDatasetAggregation 
SET MaxDataAgeDays = 60 
WHERE GroomStoredProcedureName = 'PerformanceGroom' and AggregationTypeId = '30'
USE OperationsManagerDW 
UPDATE StandardDatasetAggregation 
SET MaxDataAgeDays = 60 
WHERE GroomStoredProcedureName = 'PerformanceGroom' and AggregationTypeId = '20'
--State Data: 
USE OperationsManagerDW 
UPDATE StandardDatasetAggregation 
SET MaxDataAgeDays = 120 
WHERE GroomStoredProcedureName = 'StateGroom' and AggregationTypeId = '20'
USE OperationsManagerDW 
UPDATE StandardDatasetAggregation 
SET MaxDataAgeDays = 120 
WHERE GroomStoredProcedureName = 'StateGroom' and AggregationTypeId = '30'
Post running the above commands use the below query again to verify if the grooming is successful or not.
select ds.datasetDefaultName AS 'Dataset Name', sda.AggregationTypeId AS 'Agg Type 0=raw, 20=Hourly, 30=Daily', sda.MaxDataAgeDays AS 'Retention Time in Days' 
from dataset ds, StandardDatasetAggregation sda 
WHERE ds.datasetid = sda.datasetid 
ORDER by ds.datasetDefaultName
Test this in a LAB First and query it accordingly and Backup the Warehouse DB as well before performing in production.
