How to disable SQL Server Enterprise Edition's data compression in preparation for migrating to a lower version of SQL

  • Article

This has been probably one of the most common issues I have come across in the past as it relates to Tfs data migration and or upgrade. 

Scenario #1: You may be upgrading Tfs on new hardware and don't have the same version of SQL Server Enterprise in production.
Scenario #2: You have done your proof of concept in a testing environment with a Enterprise edition SQL Server, and now need to move to production where you only have SQL Server Standard Edition

Whichever the scenario, here is a quick solution that MUST be executed prior to the database backup, copy, restore steps.

Run the following command against the SQL Server Enterprise instance.

 EXEC [dbo].[prc_EnablePrefixCompression] @online = 0, @disable = 1

 

Please do not hesitate to share you experience.

Cheers!

    This procedure can be used only on TFS databases. If you want to disable copmpression for other DB you have to do something like this: SELECT SCHEMA_NAME(sys.objects.schema_id) AS [SchemaName] ,OBJECT_NAME(sys.objects.object_id) AS [ObjectName] ,[rows] ,[data_compression_desc] ,[index_id] as [IndexID_on_Table] into #compr FROM sys.partitions INNER JOIN sys.objects ON sys.partitions.object_id = sys.objects.object_id WHERE data_compression > 0 AND SCHEMA_NAME(sys.objects.schema_id) <> 'SYS' while exists(select 1 from #compr) begin       declare @i varchar(200) = (select top 1 [ObjectName] from #compr)       print @i       exec ('ALTER INDEX ALL ON '+@i + ' REBUILD WITH (DATA_COMPRESSION = None)')       delete from #compr where [ObjectName] = @i end drop table #compr
