I'm beginning to plan a complete redesign of our departments intranet pages. As it stands, every department gets their own folder within root. They all share the same look and feel but don't use CSS everything in each file is straight up static text. Basically, if a change has to be made to the header, every file must get changed. The number of files is somewhere in the hundreds. Since we're in the process of getting a new look & feel, I figured this would be the appropriate time to redesign the structure as a whole as well. My idea was to create a new C# Web Project to utilize the C# Master Pages. Within that project, each page would use the master page. Since I know they like to make many minor cosmetic changes, master pages would make things much simpler and quite frankly, I don't have time to manually edit a header 564 (random) times. The other aspect of this site is that the root would contain a documents folder within sub folders pertaining to each fo our departments.
Guess my question is, has anyone tackled an issue like this and could shed some light as to how they fixed it.
Also, would it be worth upgrading IIS and .NET to their latest version? And how much would this change cost?
Thank you.
