Upgrade MS SQL Server 2000 to 2008


I have a 32 bit MS SQL Server 2000 datase. But now they are going to upgrade the server to version 2008 which is 64 bit. How do I do that?

You can backup databases and restore on the new instance (and check the compatibility issues).
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

I only want to upgrade the database itself. MS SQL Server 2008 R2 will be installed on a fresh installation of MS Windows Server 2008 R2. I have to copy the data only  from the old, 2003, server to the new one.

you should backup your DB first and also the master DB , backup your logins if you r using Sql Authentication

Hi,

In general, it's a piece of cake. We do that exact thing all of the time, with no problems. Functionality of pure t-sql code is identical (64 bit just performs better ;-).

The one exception to this that I have encountered is extended stored procedures. Since these are written in C they would have to be recompiled as 64 bit binaries. Even then, no source code changes should be required.

If you aren't using extended stored procs you should have no problems.

Hi asimnazir123
I once upgraded from MS SQL Server 2005 to 2008. And the only thing I had to do was re attaching the database to the new SQL Server. Is that the same procedure for 2000 to 2008?

Dear Frans,

If I understand you have the 'detached' file then I think you cannot simply attach the file, because the 'detached' file aren't compatible between SQL Server version.

NB: if you backup-restore a database between SQL server version, the restore action upgrade the version of the database file.

I think you should attach your file on an original SQL server version, do a backup and restore it on you new SQL Server.
