Migration SAP SolMan 7 MSSQL 2008 R2 Enterprise Edition to MSSQL Standard Edition

Question

Hello,
I try to migrate a databse on Windows MSSQL 2008 R2 ENTERPRISE EDITION to
MSSQL 2008 R2 STANDARD EDITION.
In the source system (MSSQL 2008 R2 ENTERPRISE EDITION) there is "table compression" and
"partitioning" active.
Unfortunately the MSSQL STANDARD EDITION doesn`t support these two features.
So a normal DB backup on the source system and restore in the destination system is not possible.
But the tables compression I can deactivte by the SQL script
SELECT DISTINCT ‘ALTER TABLE [' + SCHEMA_NAME(schema_id) + '].[' + NAME + '] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);’
FROM sys.partitions p
join sys.objects o
on p.object_id = o.object_id
WHERE o.TYPE = ‘u’
and data_compression_desc != ‘NONE’
UNION
SELECT ‘ALTER INDEX ALL ON [' + SCHEMA_NAME(schema_id) + '].[' + NAME + '] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);’
FROM sys.partitions p
join sys.objects o
on p.object_id = o.object_id
WHERE o.TYPE = ‘u’
and data_compression_desc != ‘NONE’
is there a way to undo or deactivate the the SQL table partitioning without data lost ?
Best regards

Hello Lydia Zhang,
thanks for your help.
For a few tables this will work.
Unfortunately I have an SAP system with thousands of tables and index`s .
With the SQL script:
SELECT
 SCHEMA_NAME(t.schema_id) AS SchemaName
,OBJECT_NAME(i.object_id) AS ObjectName
,p.partition_number AS PartitionNumber
,fg.name AS Filegroup_Name
,rows AS 'Rows'
,au.total_pages AS 'TotalDataPages'
,CASE boundary_value_on_right
    WHEN 1 THEN 'less than'
    ELSE 'less than or equal to'
 END AS 'Comparison'
,value AS 'ComparisonValue'
,p.data_compression_desc AS 'DataCompression'
,p.partition_id
FROM sys.partitions p
JOIN sys.indexes i ON p.object_id = i.object_id AND p.index_id = i.index_id
JOIN sys.partition_schemes ps ON ps.data_space_id = i.data_space_id
JOIN sys.partition_functions f ON f.function_id = ps.function_id
LEFT JOIN sys.partition_range_values rv ON f.function_id = rv.function_id AND p.partition_number = rv.boundary_id
JOIN sys.destination_data_spaces dds ON dds.partition_scheme_id = ps.data_space_id AND dds.destination_id = p.partition_number
JOIN sys.filegroups fg ON dds.data_space_id = fg.data_space_id
JOIN (SELECT container_id, sum(total_pages) as total_pages
        FROM sys.allocation_units
        GROUP BY container_id) AS au ON au.container_id = p.partition_id
JOIN sys.tables t ON p.object_id = t.object_id
WHERE i.index_id < 2
ORDER BY ObjectName,p.partition_number;
GO
Output:
SchemaName    ObjectName    PartitionNumber    Filegroup_Name    Rows    TotalDataPages    Comparison    ComparisonValue    DataCompression  
 partition_id
swp    /BI0/F0CCMARSH    1    PRIMARY    0    0    less than    NULL    NONE    72057613126729728
swp    /BI0/F0CCMAWDD1    1    PRIMARY    0    0    less than    NULL    NONE    72057613127516160
swp    /BI0/F0CCMAWDD2    1    PRIMARY    0    0    less than    NULL    NONE    72057613128237056
swp    /BI0/F0CCMAWDH1    1    PRIMARY    0    0    less than    NULL    NONE    72057613128957952
and so on
I got about 5000 tables .
Is there a way to delete all index on the partioned table an create a new with one script ?
Best regards
