<p>I've read a number of posts touting the merits of migrating from VS 2005 to 2008. However, I'd love to hear what the various pitfalls are in actually doing the migration. We're about to migrate and I'd prefer knowing what speed bumps to anticipate and plan for instead of discovering them by surprise along the way. Any helpful guidance on this would be much appreciated so that the process is as painless as possible.</p>

<p>Oh, we're primarily a C++ development house, with a handful of moderate size products and a bunch of small ancilliary tools. We use external makefiles for everything so that all builds are readily automated. Specific insights about what to expect when migrating this type of development operation would be most helpful.</p>

<p>Thanks in advance for the help!</p>

The
only
issue I have had with Visual Studio 2008 is that it was quite slow until I tweaked it a bit.  I was running into a delay coming out of Debug mode on the order of 8-10 seconds or so - was
quite
annoying.  SP1 helped out as did modifying some IE settings.
But otherwise, I've been happy with it.
