Installing SQL Server 2000 after 2005

I use SQL Server 2005 (Express); I have a client now that uses 2000 and to support this client, I need to install SQL Server 2000 Enterprise Edition on the same pc.  Can I do this?  Any advice is greatly appreciated - I don't want to try it until I'm pretty sure I won't mess up the 2005 version!

yes, you can install both versions of sql 2000 and sql 2005 on the same machine.
just make sure you get different instance names.

you need reinstall sql server

also you can not install "SQL Server 2000 Enterprise Edition" on PC if OS not like:


SQL Server 2000 Enterprise Edition and Standard Edition can run on the following operating systems:
Windows Server 2003 R2
Windows Server 2003, Standard Edition1
Windows Server 2003, Enterprise Edition2
Windows Server 2003, Datacenter Edition3
Windows® 2000 Server
Windows 2000 Advanced Server
Windows 2000 Datacenter Server

Open in new window

Also you can run your client's SQL 2K database inside SQL 2005 using "SQL Server 2000 Compatibility Mode"
This way you will not waste your resources by running two different version of SQL Server.
