SQL 2005 and SQL 2000, one Dev server, co-existence

We have many SQL 2000 servers and are beginning to plan our upgrade path.  Has anyone had experience running SQL 2005 and SQL 2000 on the same machine   This would be in a development environment to aid in our analysis.  Is this possible   Any issues or concerns

SQL 2005 and SQL 2000, one Dev server, co-existence

    If you want to install them side-by-side you need to provide a unique instance name for the SQL Server 2005 installation. From your comments it sounds like SQL Server 2000 is installed as the default instance (MSSQLSERVER). When installing SQL Server 2005, on the Instance Name dialog select Named Instance and type in a unique instance name (i.e. FOO). You won't be prompted to upgrade your existing SQL Server 2000 instance and SQL Server 2005 will be installed side-by-side.

    As Greg stated, this is a supported confirguration. You should install SQL Server 2005 after SQL Server 2000.

    I'm trying to install SQL 2005 on SQL 2000 box. When I'm prompted to upgrade SQL Server Database Services 8.00.761, is this something I want to do if I want to keep SQL 2000 When I don't select this upgrade option setup tells me it won't install this component.

    I'm bit disappointed with lack of information about this topic. I would have thought most people will ask this question in the beginning before migrating.

    Hello Dan,

    Your explanation is clear to me, however one thing isn't clear yet...

    If I install only SQL 2005, can I support the SQL 2000 servers with it e.g. Can I edit my 'old' DTS, my 'old' measures within MSAS, etc Or do I need the SQL 2000 for these things

    Thanks in advance,
    Marco.

    This is supported, and you shouldn't have any problems as long as you install SQL 2005 after SQL 2000.

    Hi Marco,

    I'm not an expert on the CDW. You should post this to: http://forums.microsoft.com/MSDN/ShowForum.aspx ForumID=84&SiteID=1 for a quicker reposnse.

    Sorry I couldn't help.

    Hello Dan,

    I tried the copy database wizard between a SQL 2000 and a SQL 2005 server. I first registered the SQL 2000 on the SQL 2005 server. I could access all the tables and views.

    Then I started the wizard and after a while a got the next message:

    "The job failed. Check the event log on the destination server for details. (Copy Database Wizard"

    In the event log I found two messages:

    "Package CDW_SERVER1_SERVER2_1 failed" Event id 12291

    and:

    "SQL Server Scheduled Job 'CDW_SERVER1_SERVER2_1' (0x2c664338B69874418A6BE999ACBC972) - Status: Failed - Invoked on: 2005-11-11 10:05:39 - Message: The job failed. The job was invoked by User DEVELOP\Administrator. The last step to run was step 1 (CDW_SERVER1_SERVER2_1_Step)." Event id 208

    So, still no database on the new server.

    Any ideas

    Thanks in advance.

    You can use the new tools to manage SQL Server 2000 databases. For the DTS question I suggest you post to: http://forums.microsoft.com/MSDN/ShowForum.aspx ForumID=80&SiteID=1

    I know you can use the new tools to upgrade your DTS packages but I'm not sure how much administration you can do to the SQL 2000 packages without upgrading them to full SQL Server Integration Services packages. We will have a download of the DTS designer that will give you full adminsitration capabilities but it's not available yet - it should be soon.

    Cheers,
    Dan
