The company I work for is preparing for application testing in IE8. Previously we have been using IE6. Many of our web applications are written in .NET 1.0 and 1.1 with more recent apps written in 2.x and 3.x. I know IE8 has an IE7 compatibility mode and it says it has a quirks mode, but most of our apps were written for 6, which is not specifically mentioned. Compatibility is for 7, which had a compatibility for 6. I do not know if that is necessarily carried over to 8. In 6 quirks mode was to run 5.5 sites without a problem. With no deeper explanation on any of Microsoft’s release notes does it mention quirks mode as 6 compliant or even 5.5, just a basis of what it is (specific DOCTYPEs or no DOCTYPEs).
If anyone could shed some light on how sites and apps designed for IE6 should run in IE8 would be greatly appreciated. If anyone else has made a similar move how smooth was the transition?
Thanks.
We made a similar switch in our company. We went from IE6 to IE8 across board, the only issues we noticed were related to styling. Now if you decide to upgrade your IIS server than that might cause some of your ASP apps to not work correctly.
