Hi
I am trying to move a database from SQL Server 7 to 2005 which has
1)40 tables
2) 70 stored procedures
3)11 tables with identity fields
Has anybody accomplished migration of a similar database type.
I did run the upgrade advisor. It does not show any major issues. However I am not sure what will be the best way to deal with tables which have identity fields.
Any help will be greatly appreciated.
Thanks!
Saleha

I did the similar thing. Just copied the table structures and T-SQL objects and there were no issues. But instead of copying it would be better to re-design the sps. SQL Server 7 is very old and 2005 is very new and it has somany features.

Did the identity fields work ok when you moved to the new server? Did the seed started from where it was left at the old server.

Hi

You can use IDENTITY_INSERT to ON for the data migration. After this use DBCC CHECKIDENT to set the new seed value:

CREATE TABLE #T (Id INT IDENTITY(1, 1), Txt VARCHAR(50))

-- Allow identity insert

SET IDENTITY_INSERT #T ON

-- Insert data into identity column

INSERT INTO #T (Id, Txt)

SELECT 1, 'Hello'

UNION ALL SELECT 2, 'World'

-- Set new seeding to 300

DBCC CHECKIDENT (#T, RESEED, 100)

-- Disallow identity insert off

SET IDENTITY_INSERT #T OFF

-- Some other test data

INSERT INTO #T

SELECT 'New World'

SELECT * FROM #T

DROP TABLE #T

The way i did is created the tablestructures with Identity columns in 2005 and set the IDENTITY_INSERT ON. Moved the data and re-seeded the Identity column.

simply

backup and restore

or

detach and attach

the SQL 7 database to the SQL 2005 server and all the identities should be fine

dont forget to update usages and rebuild indexes afterwards
