SQL Server 2005 and 2008 on same developer machine?

SQL Server 2005 and 2008 on same developer machine?

"Has anyone tried installing SQL Server 2008 Developer on a machine that already has 2005 Developer installed?

I am unsure if I should do this, and I need to keep 2005 on this machine for the foreseeable future in order to test our application easily. Since I sometimes need to take backup files of databases and make available for other people in the company I cannot just replace 2005 with 2008 as I suspect (but do not know) that the databases aren't 100% backwards compatible.

What kind of issues would arise? Do I need to install the new version with an instance name, will that work? Can I use a different port number to distinguish them?

I found this entry on technet: http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=3496209&SiteID=17

It doesn't say more than just yes you can do this and I kinda suspected that this was doable anyway, but I need to know if there are anything I need to know before I start installing.

Anyone?"

"Yes this is possible. You will have to create a named instance not used by another version of SQL Server as per the previous answer and version 3.5 of .Net installed. Works great!!

Here the list of prerequisites:

.NET Framework 3.5 SP1
Windows Installer 4.5
Windows PowerShell 1.0"

If you have Visual Studio 2008 installed you will get a validation error and you cannot install SQL server 2008 until you install Visual Studio 2008 SP1. If you don't have Visual Studio 2008 installed it should not be a problem. So if you do have Visual Studio 2008 wait till August 11th since that is the day that Visual Studio 2008 SP1 will ship

"I believe that this is perfectly possible. I am currently running both SQL Server 2000 and SQL Server 2005 on my development server while I transfer applications over.

The only thing you will have to do is create a new instance which isn't already being used by SQL Server 2005.

As with anything new, there will probably be some bugs, however, it should generally ""just work""."
