Hi -
We are considering upgrading from SQL 2005 to 2008 and, unfortunately, I just have one server for testing.

I have found a few articles and posts on news groups regarding a side by side install, some indicate no problems and some indicate that there can be problems.

The one common thread is that you have to install SQL 2008 as a Named Instance. Not a big deal. However, are there other issues that I might run into?

We use SSIS in 2005 extensively, so I would think that there might be an issue with SSIS in 2008 being able to open/run the 2005 SSIS packages? Or is this backwards compatible? And, would I need to install VS.Net 2008 as well?

Thanks for any help or ideas.

I run 2005 and 2008 in dev just fine, with 2008 being a named instance. The only issue is that the 2008 mangement studio cannot connect to 2005 services other than Database Engine (like Analysis Services, Integration Services, etc). And I think I have the full version of 2008 and not a beta version installed.

Thanks for the information. It seems like we should be all right in installing the two versions side-by-side. Naturally...we'll have some contingency plans in case things don't work out.

Thanks.
