I have a legacy .NET site that has been around since the 1.1 days. As I've upgraded my VS, I've upgraded the target framework as well. Currently the site is running 3.5. I just got VS10 and it is asking me to upgrade the site to 4.0. However, my (shared) server is still running 3.5 and I can't upgrade it. Is it safe to upgrade the site to 4.0 while the server running it is 3.5?

No its not safe for you to upgrade, your website wont run.

When i upgraded to VS10 i forgot to upgrade my server. It was showing errors about the unknown tags VS10 adds during the upgrade process, which i imagine is just the start.

No, I wouldn't think so. All of your basic assembly information in your web.config will be changed to target the 4.0.0.0 versions of dll's and not the 3.5.0.0 versions. As a result, you will generate a lot of missing assembly error messages. PS - VS2010 should only prompt you once...
