Couple months ago I had to re-install my exchange server, the 5.5 media we supposedly had before I got here was missing so I had to use an eval version of 5.5 to get up an running again. I've since purchased new media and updated liscenses from my vendor and now need to install the full version over the eval version so my server doesn't stop working on 4/3. Can I just run the install and have everything work ok? Or do I need to remove the eval first, install, and recreate my information store? Also, I'm assuming I'll have to re-apply SP4 after install correct? Thanks for any advice. ===================== Use the below link for Archives, and to set your preferences. http://thethin.net/exchangelist.cfm
