Reduce database size
I have a Dimension server logging 55 watchguards. I am removing 6 of them and setting up a dedicated dimension server for those 6 for a client that wants a lot longer retention period. I recently upgraded the database size by double to 600GB (for them). I am setting up a new raid on an old server of 300GB 15k drives so that dimension will hopefully run better because right now its dreadful. This means I need to reduce the size from 600g to 300gb (well like 280). When I added space I simply added it to the VM and rebooted dimension and it picked up the change and grew. Is there a way to shrink the DB size once it has been increased or should I just setup a new server, reconfigure all the settings (email alerts, a couple reports to customers, etc) and change the IP address to that of the old one? IF I just setup a new one, can I export all the settings to the new one? I took a quick look earlier but didn't see a settings export.
Looking for insight on easiest path as I don't have much time to work on it.
