We're about to patch exchange, should we wait for the next tool?

Q: We became concerned when the recommended approach seemed to have changed. We have patched all Server OS's. Now, we are planning on patching the Exchange apps, and then running the Exchange tool. Should we wait for the updated tool to come out next week?
A: The Exchange Calendar Update tool V2 was released on 2/21. You can visit support.microsoft.com/kb/930879 for more information and to obtain the download.
