Sql servwe 2000 and 2005 in a same server

  • Hi All

    Is it possible to run sql server 2000 and sql server 2005 in a same

    machine.

    After i install sql server 2005 ,I'm not able to access sql server 2000.

    How can i do this.Pls share your valid ideas with me

    My OS is windows server 2003

    Thanks Josh

  • Sure it's possible. 2000 has to be installed first and can be the default or a named instance. SQL 2005 must be installed second and must be a named instance.

    Make sure when you install 2005, you specify that it's a new named instance, not an upgrade of the existing 2000 one.

  • I have the very same configuration on my development machine. I have full access to both 2000 & 2005 servers and client tools. As Gail said, make sure you do not make it an upgrade, 2005 must go on as a named instance.

    You can then connect to each instance as (assuming your computer is called COMPUTER)

    2000: COMPUTER

    2005: COMPUTER\sql2005

    where sql2005 is the name you gave to the named instance in SQL Server's installation.

  • Hi gail

    thank you for your valuable advice

  • Also if you are going to install the DTS components for SQL 2005 make sure you are on SP4 for SQL 2000 or Enterprise Manager won't work anymore.

    The 2005 instance does not have to be a named instance for both to live happily on the same machine.

  • This is even recommended configuration for upgrade. Remeber that in cluster you can even run both on the same default port 1433 (not recommended).

  • I have succesfully build SQL Server 2005 as the first and default instance, then installed SQL Server 2000 as a named instaNCE.

    Why do you want to retain a SQL Sever 2000 instance?
