Background:
My server has 2 commercial products. Product A relies on SQL Server 2005 Express and Product B relies on SQL Server 2008 R2.
Product A will be updated which requires an update to SQL Server 2008 R2 Express 64bit (cannot use the full version).
Issue:
I cannot update 2005 express to 2008 express because 2005 express is a 32bit installation. I plan to uninstall 2005 and then install the necessary express version, but I don't want to interfere with the SQL Server 2008 R2 installation in the process. I've searched a bit but I can't find much information on this type of problem. If anyone can provide any information, write-ups, etc. it would be greatly appreciated!
