Vault Files convert from Year version to the Next?

Hi,
How do you recommend that you convert Vault Files from one Yearversion to the Next (i.e. SW2008 to SW2009)? What is the best wayto do it? Let it run on weekends.. or over night? Any special tips?I started to do it one late afternoon and it locked us out of thevault and it took me a while to figure out how to unlock things.Has anyone had any problems with the process? The dialog messagesabout converting get annoying after awhile.
