I am responsible for migrating an Asp.net 2.0 web application with a Sql Server 2005 backend on a shared server at a hosting company. It is a relatively small app but it is mission critical for a number of small businesses.
I am migrating it to an Asp.net 4.5 server with Sql Server 2012 on the backend.
I want to prevent having to revert back to the Old App from the New App after my clients have started entering data in the New App.
I plan to thoroughly test the New App to try to trigger any possible problems.
Does anyone have any experience and suggestions that may be pertinent to this migration?
Thanks in advance.
