I am trying to determine if there are any problems/gotchas/known issues/etc. running both Microsoft SQL Server Express Edition (2005) and SQL Anywhere 10.0 concurrently on the same application server. We already have an app using SQL Server Express for the backend loaded on our primary application server, and now have a request to load Quickbooks Accounting 2009 (which uses SQL Anywhere 10.0 as best I can tell) on it as well. I virtualized the machine to ESXi to test the installation and make sure that nothing broke right off the bat, but before I sign off on it, I wanted to see if there are any issues that may manifest themselves later on down the road. Any personal experiences you can relate, or google results (or whatever) are welcome.
